Bug Type: Performance problem

Comments:
Note that under UNIX, execution time relates to the actual CPU time consumed by PHP, which may be
very different (less) than the actual time that passed. sleep(), for instance, does not consume any
CPU time, so it will never trigger the execution timeout.

I can't reproduce this with latest CVS. If problem
still persist with PHP 4.0.5 or with latest CVS snapshot
from http://snaps.php.net/ reopen this bug report.

I'm re-filing this as a bug report.
It appears that set_time_out() is acting inconsistant.
The following code stops after 5 seconds as you would expect:
set_time_limit(5);
while(1) {
$i++;
}
While this code continues executing indefinitely:
set_time_limit(5);
while(1) {
$i++;
echo "$in";
}

documentation is not clear enough on what "excecution time"
the max_execution_parameter does limit.
try the following:
<?php
set_time_limit(1);
while(1) sleep(1);
?>
on my machine that runs much more then one second, while:
<?php
set_time_limit(1);
while(1);
?>
stops after 1 second as expected.
That difference is never mentioned in documentaion.
While the usage of PROF timer make sence sometimes the parameter name "max_execution_time"
suggests the "real" time limit so that
<?php
set_time_limit(30);
sleep(3600);
?>
should be terminated on timeout after 30 seconds.
