from the debug log Alex sent some time ago I see that it is a real
thread calling thr_alarm and sending the signal 14 (in the log below
it is thread 11).
Maybe the Solaris debugger does not show the connection thread if
it has called for thr-alarm, or if it is cached.
>From the discussion I have got the impression that there is a
phantom connection left hanging in Solaris: the MySQL server
detects this connection and tries to answer to it, but there is
no client process behind the connection.
