[clug] killing a looping / hung script?

[Paul Wilson]

I have a perl script which occasionally goes into a hung or wait state, and
wanted to know is there a standard way to automatically kill this process
after some timeout (eg 1 min).
Note the perl script is doing a Serial port read and for some reason it
waits if there is an issue with the Arduino.

ie can I use some sort of wrapper script to check this state and kill it?
