AFAICT it does not. In vnc_refresh(), there is a call to rfbProcessEvents, 
which says to select() the socket(s) for 0 microseconds. Same thread.

Now, there is a facility in LibVNCServer to take advantage of pthreads, 
and in some applications it is actually better to run a background thread 
to handle all the VNC stuff. But it is not used in QEmu.
