[log4perl-devel] Config file reload on signal

[<msc...@ao...>]

Hey,

just had an idea: How about if we add functionality to init_and_watch in Log::Log4perl to not only watch config files but to also be able to listen to (Unix) signals instead? Yeah, yeah, I know signals are unreliable and can cause all kinds of crazy stuff -- but how about if we have the signal handler just set a global variable, which is checked by the watcher code instead of calling time() all the time?
Please take a look at the patch below, and let me know what you think ... the addtl. syntax is:

   init_and_watch($file, 'HUP'); # will listen to SIGHUP

I've also attached a test file.
