My assumption is that the other Unixes weren't looking at interrupt timing to begin with, i.e. they've always been as starved for entropy as Linux eventually became. That being said, does VXWorks even *have* an OS provided strong random number generator? Windows has CryptGenRandom, which AFAIK doesn't block, and survives everything but VM suspend/restore. --Dan
