Rainbows! isn't supported on non-Free operating systems even though it
probably works.

OSX is broken here for returning RLIMIT_INFINITY (9223372036854775807).
Working around broken things non-Free systems just encourages them
to stay broken.

If it were a Free system, I /might/ work around it while simultaneously
getting it fixed upstream[1].  But this is a non-fatal error and just
writes to the log, it won't stop Rainbows! from working.  You can still
set the limit higher before you start the process.

If you're stuck on OSX, pressure OSX devs into fixing it.  Remember, you
(or your organization) _paid_ for OSX.

Reading over the code in the Ruby trunk and ruby_1_9_3 branch, it looks
fine and runs fine on GNU/Linux.



[1] - we've done this in the past with MRI 1.8/1.9 bugs and have gotten
      everything fixed upstream
