[Gllug] perl question

[Jack Bertram]

I have a little perl script which uses ncurses to display a list of
mailboxes, checks new mail, allows me to run various commands and so on.
It works perfectly, but - essentially because the main body of the
program is an infinite loop which checks for keypresses and for mailbox
updates - uses 50% of my CPU time.  No problem on my main machine but a
bit of a pain for the little arm box that I'm going to migrate to.

Anyone know if there is a canonical way of writing the main loop to stop
this happening in perl?  I only need to poll the mailboxes once every
few seconds, but I need to respond to keypresses instantly, so a sleep()
call won't work.

thanks,
jack
