Changeset 54480 in vbox for trunk/src/VBox/HostDrivers/Support

Message:

SUPDrvGip.cpp: Double the timeout to just below 2ms to make it less likely that we time out before we get anything done on slow machines. Windows doesn't seem to care about how long IPI work takes, fortunately. :-) (Usually the job is done in < 50 us, this is just making sure the worst case scenario works.)
