pcntl_alarm() doesn't work with apache_worker (multithreaded)

$subject says everything: when php runs under a multithreaded apache
pcntl_alarm() doesn't work: the alarm is never delivered.

My version of php is 5.2.3, but also all versions I tried of 5.1 work
the same.

http://us2.php.net/manual/en/ref.pcntl.php
"Process Control should not be enabled within a web server environment
and unexpected results may happen if any Process Control functions are
used within a web server environment."

Don't do that.
:-)

It MIGHT happen to work in a non-multi-threaded web environment, but
I wouldn't count on it as it's pretty clearly documented not to.

YMMV

That's pretty much expected since your web-server is multithreaded, while
"alarm() arranges for a `SIGALRM` signal to be delivered to the **process** in seconds seconds."
