Has anyone tried using the microsecond counter from unix as a random
source ? Its obviously *not* going to be good if you want a continuous
stream of random numbers, but if you need them just 'every now and then',
what about it ?
This should be in an FAQ: Unixes have different levels of granularity
in the microsecond counter; some systems may only have a 10 ms (that's
10000 microsecond) resolution to their clock. So you can't necessarily
depend on a getting lot of bits of randomness from this method.
