 I forgot to run procmon before closing pidgin, and it would have been
 awkward to log back in 10 minutes after saying good night to everyone. I
 ran procmon anyways while it was already frozen, in case it might catch
 something interesting happening in that infinite loop, but it didn't log
 anything for the include filter process name = pidgin.exe, and no other
 filters.

 There were no still-open connections according to TCPView.
