Bug description: sleep() not always accurate
Description:
------------
When running sleep(), I noticed it does not always pause the script for
the exact amount of time. Although the difference is no doubt
neglectible, it is still noteable.
Reproduce code:
---------------
<?php $st = array_sum (explode (' ', microtime ()));
sleep (1);
echo round ((array_sum (explode (' ',microtime ())) - $st), 7); ?>
Expected result:
----------------
I expect to see values ranging around 1.0000001 to 1.01 (depending on
lag).
Actual result:
--------------
It returned the following: (including server lag)
0.9998388
0.9999161
1.001672
