The parent is notified of which signal killed a child. If you wanted to monitor that, you could write a wrapper.
use IPC::Open3 qw( open3 );
my $child_pid = open3(
'<&STDIN',
'>&STDOUT',
*CHILD_ERROR,
@ARGV
);
my $error = '';
1 while read(CHILD_ERROR, $error, 64*1024, length($error));
$error .= "\n"
if length($error) && substr($error, -1) ne "\n";
waitpid($child_pid, 0);
my $code = 0;
if ($? & 0x7F) {
$error .= "Child killed by signal ".( $? & 0x7F )."\n";
$code = 0x80 | $?;
}
elsif ($? >> 8) {
$error .= "Child exited with error ".( $? >> 8 )."\n";
$code = $? >> 8;
}
if (length($error)) {
# Email $error here.
}
exit($code);
(As you can see, you no longer need custom handlers for warnings and exceptions in the script itself, unless you want to add stack backtraces.)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
