The problem is that i tried to reproduce this behavior locally on Ubuntu running this test (and the simplified version of it) literally millions of times. The only time it fails is when it is run on mach5 and even then it fails very rarely - once per hundreds of runs. The changes here - especially forcing the resize - seems to eliminate the problem with mach5.
