/tmp is a damfool place to have put the socket file, no doubt about that.
But we are stuck with it now if we don't want to break existing
applications --- the location of the socket file is a critical hardwired
part of the wire-level protocol, since the client and server MUST both
know it *before* any communication happens.
This was argued back around 6.4, IIRC, and we decided to do nothing.
The argument in favor of doing nothing seems even stronger now, with a
couple more years worth of existing clients out there...
Solutions:
1. Tweak your tmp-cleaning cron job to not remove the socket file.
2. Use IP instead of Unix-socket connections, so that your clients
don't care whether the socket file is there or not.
