Re^4: Print inside SIGNALS

If your C library's print function isn't re-entrant (many aren't), then there's always a chance that weird things happen when the signal goes off while your code is printing something.

That's not true for two reasons:

print doesn't use clib.
Since Perl 5.8.1, signals are deferred to be handled between Perl ops.

Thanks for the correction! The rule "don't print in signal handling" stuck with me for too long, I should have checked this.	[reply]
