NAME
       Munin::Common::Timeout - Run code with a timeout. May nest.

SYNOPSIS
	use Munin::Common::Timeout;

	do_with_timeout(50, sub {
	    # ...
	       do_with_timeout(5, sub {
		       # ...
		       # ...
	       });
	    # ...
	});

DESCRIPTION
       See also Time::Out, Sys::AlarmCall

SUBROUTINES
       do_with_timeout
	    my $finished_with_no_timeout = do_with_timeout($seconds, $code_ref)
		or die "Timed out!";

	   Executes $block with a timeout of $seconds.	Returns the return value of the $block if it completed within the timeout.  If the timeout
	   is reached and the code is still running, it halts it and returns undef.

	   NB: every $code_ref should return something defined, otherwise the caller doesn't know if a timeout occured.

	   Calls to do_with_timeout() can be nested.  Any exceptions raised by $block are propagated.
