Latest Beta has a delay in switching desktops

[ajbastien]

There seems to be some sort of delay periodically when switching desktops. Then when I try, I press the hot key multiple times and nothing happens. It takes about 10-20 seconds before switching happens. Is there some single threaded network checks happening? My machine is quite fast and has a lot of memory.

This is my only issue with this latest version!!! Very nice work!!
