kill -9 wouldn't kill it? That's usually not a problem with the program
itself.

This means that some process is doing something for a long time (5 mins
or more) while another process is trying to access the mailbox.
Typically this means that one connection is fetching lots of messages
while another tries to open the same mailbox.
No real fix for 0.99. 1.0-tests don't have this problem anymore. I
don't think this is a real problem though, mostly just annoying in log
files.
