I forgot to state what Yotam already pointed out in his previous email: Of course for the below to work, one also has to introduce a mutex which is held in the "actual screen update" code, and also by copyRectToScreen etc.

I have no idea how expensive semaphore operations are on the PSP, but the MIPS processor in it, as far as I know, support atomic memory operations, which should in theory make for a quite effective semaphore implementation. Of course I have no idea whether that is actually how they implement it ... :)
