Re: Re-exec in perl

Here's a possibly relevant note in the docs for both "alarm" and "sleep": It is usually a mistake to intermix "alarm" and "sleep" calls, because "sleep" may be internally implemented on your system with "alarm". On Tue, Oct 4, 2016 at 1:34 PM, Chas. Owens wrote: > The first alarm

Re: Re-exec in perl

The first alarm is in a different process (same PID different process) due to the exec. I am not sure what is happening, but in general it is never a good idea to do anything complex in a signal handler. On Tue, Oct 4, 2016 at 4:21 PM Shawn H Corey wrote: > On Tue, 04 Oct 2016 19:32:44 + >
