 # This test fails with "Too many open files" on the Mac OS buildbot.
 # This is expected as MacOS by default runs with a very low number
 # of allowed open files ('ulimit -n' says something like 256).

 # These tests pass on MacOS 10.8.2 but fails on the buildbot machines
 # that are running an earlier version of MacOS. The issue is that the
 # old version of MacOS does not expand the precomposed utf-8 it gets
 # from the VM before comparing it to the decomposed utf-8 used for the
 # file system.
