Some more info on this:
I defined CVS_RMDIR to point to my own function that would print a message
and then fork and exec /bin/rmdir with the directory as an argument, and
recompiled cvs.  Running cvs commit now resulted in the following:

$ /usr/src/cvs-1.11.0/build/src/cvs commit -m "" aaaa
Checking in aaaa;
/export/home/igor/testrepository/aaaa,v  <--  aaaa
new revision: 1.11; previous revision: 1.10
done
Attempting to remove directory '/export/home/igor/testrepository/#cvs.lock'
rmdir: `/export/home/igor/testrepository/#cvs.lock': Permission denied
cvs commit: failed to remove lock dir /export/home/igor/testrepository/#cvs.lock: I/O error
$ /bin/rmdir /export/home/igor/testrepository/#cvs.lock
$ echo $?
0
$

Any ideas on how to proceed with this would be welcome.
	Igor
