[Spice-devel] [PATCH spice-xpi] wait for the socket file

[Peter Hatina]

Hi,

in a log (rhel) and also in the debug messages, there sometimes appear
messages, that a controller could not connect to a socket file
(int SpiceController::Connect()). This is caused by the fact, that we try
to connect before the socket is present. I added this simple poll loop to
wait for the socket file to be created.

Any opinions?
