Subject: Graceful timeout

Hello!

Currently we can use set_time_limit() to specify that our script will run
by some seconds before we get "fatal error: maximum execution time of 1
second exceeded". And we can't catch it and keep running.

I believe that it is interesting to create a function that is able to limit
processing and stop when the time limit is recovered.

$completeRun = set_time_limit_callback(function () {
    sleep(2);
}, 1);

var_dump($completeRun);

Where $completeRun will be TRUE only if callback could run until it
returns, and FALSE if timeout.

It should be very useful when we need works with external resources, like
RESTful, where timeout can occur and we need a better way to work with
that. Or when we have few seconds to run a process.

What do you think?


Atenciosamente,
David Rodrigues
