As already mentioned by others on this list, this was fixed in the
tree very recently, thanks to you and your co-worker for pointing it
out.
I'm curious though - how does a continuous stream of zeroes break your
unittests ? I agree that it's pretty debianesque randomness (random()
is bad, but not *THAT* bad ;), but keep in mind that any RNG could in
theory produce an arbitrarily long sequence of zeroes too.
Can you provide some insight ?
Cheers,
Paul 'WEiRD' de Weerd
