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 occurred.

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