I agree that we need to solve the problem you were seeing originally. Good to hear that the new one goes though.

Hi Toby,

It's amazing, doing GlobalGoto unthreaded driver solved my problem, at
least during all the test I did at my (slow) home PC. Soon I'll try
how it behaves on my killer high-end PC at work (for test completeness).

New (unthreaded) version of globalgoto (now called globalgoto2) is here:
http://king.net.pl/playercontrib/plugins/player2.2/globalgoto2-20090522.tar.gz
Since it is not threaded driver, I suspect it can also be compiled with
Player-2.1.x.

Still I'm not convinced that this is the best way of solving communication
problems. If we make all message-driven drivers unthreaded (see
cameracompress and other heavy computing things), whole Player server will
suffer from huge slowdown.
