Re: svn 1.2.1 os x: make check fails b/c of too many open files

I think it must be an OSX thing, I can't reproduce it on my Linux box.

This test runs 17 diffs one after the other, it doesn't use an explict
subpool. 'bar10' is one of the files in the 10th diff, so it appears
to have run 9 diffs before running out of file handles.

>> PASS: diff-diff3-test 3: 2-way unified diff where output is suspect

main() clears the test pool before running each test. That appears to
be enough to make test 3 work after test 2 above fails

On my linux box I can do 'ulimit -n 7' (max 7 open files) and run
diff-diff3-test without a problem. If I do 'ulimit -n 6' all the
tests fail. In particular the second test fails on the first of the
17 diffs, not on the tenth ('foo4' rather than 'bar10'):

svn_tests: Can't open file 'foo4': Too many open files
FAIL: lt-diff-diff3-test 2: 2-way unified diff and trivial merge

We need someone with an OSX box to debug this.
