[Spread-users] Cleanup of socket file

[Johannes Wienke]

Hi everyone,

we are working in a multiple user environment on Linux and constantly
had problems with left-over socket files in /tmp from spread. Once one
user has used spread and stopped the daemon another user on the same
machine is unable to start spread again on the same port because the
/tmp/4803 or whatever port file is still existing with permissions
preventing a deletion.

Attached is a prototypical patch against the current 4.4 beta release
that adds a signal handler to remove this file. I haven't tested this on
Windows and other esoteric platforms so it probably needs some fixes for
those. But it would be nice if this functionality could end up in the
final release.

Cheers,
Johannes
