Actually, it was a bug in signal handling. People who saw this might try
out my pre-patch-1.3.82 on ftp.cs.helsinki.fi which should fix it.

NOTE!! It's a pre-patch for a very good reason: it has some problems in
other areas. I don't recommend running this for anything that is
critical, but if you want to live dangerously..
