Release Name: 0.2.0
Notes:
Zbatery is an HTTP server for Rack applications on systems that either
do not support fork(), or have no memory (nor need) to run the
master/worker model. It is based on Rainbows! (which is based on
Unicorn (which is based on Mongrel)) and inherits parts of each.
Zbatery supports your choice of all the thread/fiber/event/actor-based
concurrency models and Rack middleware that Rainbows! supports (or will
ever support) in a single process.

errors more reliably.

disable more Unicorn methods
init_self_pipe! and trap_deferred are worthless and
possibly harmful to us

MRI 1.8 thread fix to avoid blocking accept()
Rainbows! commit ee7fe220ccbc991e1e7cbe982caf48e3303274c7
Under MRI 1.8, listen sockets do not appear to have the
nonblocking I/O flag on by default, nor does it set the
nonblocking I/O flag when calling #accept (but it does
when using #accept_nonblock, of course).
Normally this is not a problem even when using green threads
since MRI will internally select(2) on the file descriptor
before attempting a blocking (and immediately successful)
accept(2).
However, when sharing a listen descriptor across multiple
processes, spurious wakeups are likely to occur, causing
multiple processes may be woken up when a single client
connects.
This causes a problem because accept(2)-ing on multiple
threads/processes for a single connection causes blocking accepts in
multiple processes, leading to stalled green threads.
This is not an issue under 1.9 where a blocking accept() call
unlocks the GVL to let other threads run.

Author: Eric Wong
Date: Mon Mar 1 10:20:32 2010 +0000
support "user" directive outside of after_fork hook
This is new in Unicorn 0.97.0, and makes sense to us since we
don't fork. It won't work as nicely with log reopening in some
cases, but it's better than nothing

Less code to maintain this way.
