[winGRASS] d.mon socket problem

[Markus Neteler]

A winGRASS problem still present is:

GRASS >d.mon x0
Socket is already in use or not accepting connections.
Use d.mon to select a monitor
Problem selecting x0. Will try once more

-> the monitor window opens, but is not yet accessible.
   The socket file in /tmp/grass-$USER/ is generated

   The background is grey

GRASS: > d.mon select=x0

-> now the monitor works (d.rast etc)
   The socket file is not touched a second time.
   The background is black as expected.

I used strace to get some debug output:

I don't know if this is the relevant extract, otherwise I can
provide the full strace log.
