I want subs to switch on and off my alarm so that i can call them when needed Why? The code you showed first is more or less the usual code for having a timeout in some long running code. (You do know the example in perlipc, right?) If you don't need a timeout, just don't mess with `alarm` and `$SIG{'ALRM'}` at all. In code: `withTimeout(30,\&doSomething,sub { die 'Oooops, doSomething was too sl +ow' }); # <-- timeout after 30 seconds doSomething(); # <-- no timeout here` [download] If you still think that you need to "switch on and off", please explain your actual problem.

doSomething(); # <-- no timeout here
