There used to be a test in regress/lib/libc/randomid/idtest.c but I can't seem to locate that in the current source tree. That tested for duplicate random numbers within a given number of calls to randomid(). I'm sure that test could be adapted for this srandom/random test case as well. Cheers, Simon.
