I've heard tell that MacOS X sets the limit on the number of open files
per-process ridiculously low by default. Something in the range of 300.

That would explain the failure.
Perhaps the test does not need so many files open all at once. On the
other hand if it's testing what used to be a performance bug where a
linear algorithm was being used for file locking, then perhaps the test
really does need lots of files to be open simultaneously rather than
just sequentially. Simon will know. If so perhaps the test can set a
ulimit to increase the number of open files allowed.
