Subject: Re: Too many open files - getcwd (Errno::EMFILE)

Yeah, attempts to narrow it down were pretty difficult ... Every time I
ran my 500 test cases, I got bit by that bug a couple of times, but it
hit different test cases on different runs. So I just locally cached
the value, calling Dir.getwd 1 time instead of a couple thousand, and
it seems to be working fine now.
