New submission from Floris van Manen:
I recently noticed that the standard random() function generates values >= 1.0
As processes are called from an event scheduler, each process has its own Random() instance.
self.random = random.Random(seed)
self.randomState = self.random.getstate()
keeping track of multiple objects:
self.random.setstate(self.randomState)
self.random.jumpahead(1)
self.randomState = self.random.getstate()
Also gammavariate() generates errors as it too makes use of the _random() call
A workaround is to check each response of random() for values >= 1.0
