Re: alarm function under while loop

Hi, Gokul.

POE::Kernel->alarm() enqueues an alarm, but it is not like the built-in =
alarm().  POE's alarms are dispatched by POE::Kernel in between =
callbacks.  Your while() loop pre-empts the dispatcher, so the enqueued =
alarms never occur.

If your program must delay there, you can use POE::Kernel->run_while() =
to run POE's dispatcher while a variable is true.  Set the variable =
false from the callback you are waiting for.
