raindrops is a real-time stats toolkit to show statistics for Rack HTTP
servers. It is designed for preforking servers such as unicorn, but
should support any Rack HTTP server on platforms supporting POSIX shared
memory. It may also be used as a generic scoreboard for sharing atomic
counters across multiple processes.

Changes:
raindrops 0.18.0
The most notable feature of this release is the addition of
FreeBSD and OpenBSD TCP_INFO support. This includes the
Raindrops::TCP for portably mapping TCP state names to
platform-dependent numeric values:

Thanks to Jeremy Evans and Simon Eskildsen on the
unicorn-public@bogomips.org mailing list for inspiring
these changes to raindrops.
There's also a few internal cleanups, and documentation
improvements, including some fixes to the largely-forgotten
Raindrops::Aggreage::PMQ class:

This is part of the stable API, so we shall document it for
others to use.
