I don't agree.  You should use it when you need a really random value and
you're willing to take the hit.  If you want to generate lots of numbers
quickly then you should use it as a seed.  If you want to generate a small
set of very random numbers rarely (as in Majordomo's case), you should use
it directly.

Besides, I thought that when the entropy pool was exhausted, current
versions just returned slightly less random data instead of blocking.
OXymoron would probably know more; he was the initial advocate of using
/dev/random on Linux to generate tokens.  I argued against it for reasons
of system dependency, but if someone wrote a transparent module...
