Release Name: 1.1.0

Notes:
Unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels.  Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between Unicorn and slow clients.

* mongrel-unicorn@rubyforge.org
* git://git.bogomips.org/unicorn.git

Changes:

This is a small, incremental feature release with some internal
changes to better support upcoming versions of the Rainbows! and
Zbatery web servers.  There is no need to upgrade if you're
happy with 1.0.0, but also little danger in upgrading.

There is one pedantic bugfix which shouldn't affect anyone
and small documentation updates as well.

    cleanup "stringio" require
    
    "stringio" is part of the Ruby distro and we use it in multiple
    places, so avoid re-requiring it.

    prefer "[]" to "first"/"last" where possible
    
    "[]" is slightly faster under Ruby 1.9 (but slightly
    slower under 1.8).

    tee_input: safer record separator ($/) handling
    
    Different threads may change $/ during execution, so cache it at
    function entry to a local variable for safety.  $/ may also be
    of a non-binary encoding, so rely on Rack::Utils.bytesize to
    portably capture the correct size.
    
    Our string slicing is always safe from 1.9 encoding: both our
    socket and backing temporary file are opened in binary mode,
    so we'll always be dealing with binary strings in this class
    (in accordance to the Rack spec).

    socket_helper: cleanup FreeBSD accf_* detection
    
    Instead of detecting at startup if filters may be used, just try
    anyways and log the error.  It is better to ask for forgiveness
    than permission :)

    socket_helper: no reason to check for logger method
    
    We only use this module in HttpServer and our unit test mocks
    it properly.

    socket_helper: tunables for tcp_defer_accept/accept_filter
    
    Under Linux, this allows users to tune the time (in seconds) to
    defer connections before allowing them to be accepted.  The
    behavior of TCP_DEFER_ACCEPT changed with Linux 2.6.32 and idle
    connections may still be accept()-ed after the specified value
    in seconds.  A small value of '1' remains the default for
    Unicorn as Unicorn does not worry about slow clients.  Higher
    values provide better DoS protection for Rainbows! but also
    increases kernel memory usage.
    
    Allowing "dataready" for FreeBSD accept filters will allow
    SSL sockets to be used in the future for HTTPS, too.

    http_response: this should be a module, not a class
    
    This affects Rainbows!, but Rainbows! is still using the Unicorn
    1.x branch.  While we're at it, avoid redeclaring the "Unicorn"
    module, it makes documentation noisier.

    tee_input: undent, avoid (re)-declaring "module Unicorn"
    
    It makes RDoc look better and cleaner, since we don't
    do anything in the Unicorn namespace.

    tee_input: allow tuning of client_body_buffer_size/io_size
    
    Some folks may require more fine-grained control of buffering
    and I/O chunk sizes, so we'll support them (unofficially, for
    now).

    test-exec: prefer ENV['PWD'] in working_directory tests
    
    We do an extra check in the application dispatch to ensure
    ENV['PWD'] is set correctly to match Dir.pwd (even if the
    string path is different) as this is required for Capistrano
    deployments.
    
    These tests should now pass under OSX where /var is apparently
    a symlink to /private/var.
