Hi Jim,
The Darwin HFS+ bug is even reproducible on Linux, on NFS mounts from a
Darwin 10.3.9 machine. Here is that same directory, of which Darwin's
readdir() bug occurred after 178 removals. Here it occurs already after
13 removals on average:
$ ll charmaps | wc -l
195
$ rm -r charmaps
rm: cannot remove directory `charmaps': Directory not empty
$ ll charmaps | wc -l

$ df -T .

This means one has to enable the workaround with 8% speed penalty on all
systems, not just Darwin...
