[Samba] smbd hanging on OS X 10.4.8

[nicerobot]

Great idea. Sorry, I should have already done that. I ran ktrace several
times letting it hang for several minutes just to check if it's polling.
All produce the same trace.
lsof doesn't show any files in /private/var/samba that don't belong to
the hung smbd process.
Also, not sure it matters but from scanning the full trace, the only
files in /private/var/samba not accessed are account_policy.tdb and
unexpected.tdb.

Here is the tail of the file from the last item printed to the console
through to my interrupt:
