Yes, I know ;-) This was my first aware. I've builded my own
randomInt(n:int) function, that harvests entropy from /dev/urandom.

Thanks anyway for the tip.

Nice! It could even be implemented as a macro! Thank you!

(But the size variable (avma-bot) gives the size of stack in "long"
type words, isn't it? It should be multiply by "sizeof(pari_sp)" or
"sizeof(long)", I guess.)

Thanks a lot!
