man urandom
When read, the /dev/urandom device returns random bytes using
a pseudorandom number generator seeded from the entropy pool. Reads
from this device do not block (i.e., the CPU is not yielded), but can
incur an appreciable delay when requesting large amounts of data.
My utility in pascal is faster than this, it does not wait.
