unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels. Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between unicorn and slow clients.
Disclaimer:
Due to its ability to tolerate crashes and isolate clients, unicorn
is unfortunately known to prolong the existence of bugs in applications
and libraries which run on top of it.

Jeremy also contributed the ability to use separate groups for the process
and log files:

There's also a couple of uninteresting minor optimizations and
documentation additions.

Nowadays, I mainly rely on systemd (and not USR2) for
zero-downtime upgrades. Also, CoW-friendliness is standard
in mainline Ruby since 2.0.
There also needs to be a disclaimer to point out the unfortunate
side-effect of robustness for hosting buggy apps.
