<plug> If you'd like to be able to have multiple alarms running, without affecting (or being affected by) other code you use which sets alarms, you could use the :OVERRIDE option of Alarm::Concurrent. One should be wary of using this option in production level code, as it overrides %SIG, but the OP's situation doesn't seem like it would be a problem. And, of course, this is just a standard warning, as I've never actually had it cause a problem for me.
