Re: Setting signal handlers considered unsafe?

On my machine:

perl, v5.10.0
Linux localhost.localdomain 2.6.26.5-45.fc9.i686 #1 SMP i686 i386
[download]

I got the following flavour of results:

localhost$ perl d.pl
  child starting
  SIGARLM: main handler
  SIGARLM: main handler
  SIGARLM: main handler
  Maximal count of pending signals (120) exceeded at d.pl line 14.
localhost$ perl d.pl 
  child starting
  Alarm clock
localhost$ perl d.pl 
  child starting
  Maximal count of pending signals (120) exceeded at d.pl line 9.
  SIGARLM: main handler
localhost$ perl d.pl 
  child starting
  Alarm clock

What exactly are you trying to do? I want to ensure that at every moment of my program's life signals are safely handled. I have already experienced strange errors which boil down to non-atomicity of setting signal handlers (a signal gets delivered in the middle of setting a handler, thoroughly confusing perl).	[reply]
