&do_program(1, 100); is a subroutine in the same script.
In a nutshell, calling the &do_program(1, 100), it will do the followings:
1) Connect to the MySql database
2) Retrive 100 domains beginning from row 1 for 100 rows in one of the tables.
3) Remote access each of the 100 domains using LWP::UserAgent
4) Then abstract the site(domain) page information
It generally takes about 2 minutes to complete all of the above steps 1 to 4.
(Notes: I've watched it ran many times, it took around that kind time to complete.)
I'm mainly trying to find out if the scripts in the eval { } will work or not.
They do not seem to work, because &do_program(1, 100) will continue to run from start to finish even though I set the alarm timeout variable, $timeout at different numbers
less than 120(2 minutes), e.g. $timeout=20, $timeout=10, $timeout=5... down to 1 second $timeout=1.
For some reason, there is no alarm signal generated in the eval {} block??
