Release Name: 4.1.0

Notes:
Rainbows! 4.1.0 - minor internal cleanups

Rainbows! is an HTTP server for sleepy Rack applications.  It is based on
Unicorn, but designed to handle applications that expect long
request/response times and/or slow clients.

* http://rainbows.rubyforge.org/
* rainbows-talk@rubyforge.org
* git://bogomips.org/rainbows.git

Changes:

There are only some minor cleanups in this release and a bump to
kgio 2.5 to remove the dependency on io/wait.  kgio 2.5 or later
is now required (kgio 2.6+ will be required in the next
release).

    remove tcp_nodelay/tcp_nopush tweaking
    
    Unicorn 4.x already defaults match those of Rainbows!
    to favor lower latency instead of lowered bandwidth
    usage.

    Revert "http_server: cap timeout at 32-bit LONG_MAX seconds"
    
    Unicorn (> 4.0.1) already handles this for us,
    not that it affects many people...
    
    This reverts commit 37c376a9253ed62d134cbb4dbc6eaecc6076c77e.

    t0044: do not assume setsockopt() finished
    
    Race conditions abound in the world of concurrency!

    Fix Fiber* and WriterThread* breakage from removing io/wait
    
    This fixes up breakage introduced in commit
    905f0ff393629ddb4d70e3dc221b016128c47415 to switch to
    kgio for timed, synchronous waiting.

    require kgio 2.5 for kgio_wait_readable(timeout)
    
    Since kgio_wait_*able in kgio 2.5 takes an optional timeout
    argument, we no longer have to load the extra "io/wait" module.
    This saves us a small amount of some memory and also removes the
    extra ioctl(FIONREAD) syscall IO#wait enforces.
    
    Like IO#wait in Ruby 1.9.3dev, kgio_wait_readable may use
    ppoll() to wait on high-numbered file descriptors as efficiently
    as it waits on low-numbered descriptors.

    bin/rainbows: release the OptionParser object from stack
    
    No point in keeping it around to eat memory.

    http_server: cap timeout at 32-bit LONG_MAX seconds
    
    We can't wait for longer than 68 years.
