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.

Thanks, pushed to raindrops.git:

a5902f243cd2 Fix queue stats for sockets with SO_REUSEPORT
I'm honestly shocked that these features get used;
I never convinced the org I worked for to use them :x
Anything else? Could tag a release in a bit...

It doesn't affect the test outcome, but it is not the intended behaviour of
the test.
We listen once to find out what port to use, then should bind with SO_REUSEPORT
N-1 times, but we are doing it N times, so we have one extra listener.
