generates numbers in a strict even-odd-even-odd pattern. The pattern
doesn't occur on *nix OSs
Reproduce code:
---------------
<?php
for (i = 0; i < 100; i++)
echo rand()."<br />\n";
?>
Expected result:
----------------
expected numbers with no noticable pattern
Actual result:
--------------
numbers were in an even-odd-even-odd pattern
