Hi Jay
Sorry for the bad explanation of my problem.
Yes my program has to continue while waiting for the timeout.
You code example doesn't work for me because my program is an entire
Catalyst application which I dont think is a good idea to put into an
eval block.
I would need the timer to run in the background and once it expires it
should execute the code.
