This can happen if the mailbox is open when the client tries to delete 
it because the Cyrus code does a chdir() to the mailbox directory when 
opening it.  Some OS don't like doing a rmdir() when the process is in 
the directory.

This is fixed in the 2.3 code, mainly because the mailbox metadata files 
can be split outside of the mailbox directory, so doing a chdir() 
doesn't make much sense in this case.
