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.

Changes:

This gets most of the improvements Rainbows! 4.0.0 got:

* client_max_header_size directive is added to limit per-client
memory usage in headers.

* An experimental StreamResponseEpoll concurrency option

* minor bugfixes, minor stack depth reduction

Since Zbatery doesn't fork workers, the ability of Unicorn 4.x
to scale to a large amount of worker processes doesn't matter
to us.
