md5 test

[Shmuel Zeigerman <shmuz@...>]

This test (from the distribution) seems to fail with probability 1/256 
(provided >= 1 sec. is allowed between the tests):

  assert(md5.crypt('a', 'a') ~= md5.crypt('a', 'b'))

This test always fails:

  local seed = '\154\21\104\72'
  assert(md5.crypt('a','a',seed) ~= md5.crypt('a','b',seed))

Whether this behavior is due to the md5 algorithm, or is this an 
implementation fault?
