poclbm/guiminer halts processing

At this point poclbm just seems to hang, ctrl-c and running it again and the problem is gone but I seem to get this a fair bit and it may be the reason why guiminer just stops processing blocks for me frequently. Interestingly though poclbm on the command-line seems more stable, so maybe the hang issue is threading or subprocess buffer-related? My apologies for the somewhat mixed bug here :(
