Raindrops 0.8.0 - real-time stats for preforking Rack servers

Raindrops is a real-time stats toolkit to show statistics for Rack HTTP
servers. It is designed for preforking servers such as Rainbows! and
Unicorn, but should support any Rack HTTP server under Ruby 1.9, 1.8 and
Rubinius on platforms supporting POSIX shared memory. It may also be
used as a generic scoreboard for sharing atomic counters across multiple
processes.

Changes: watcher updates

There are various updates to the Raindrops::Watcher Rack app.
Most notably, the timestamp where the a statistic first and last
hit its peak value (active/queued connections) is captured.

As usual, the latest Raindrops::Watcher is running at:
