Here is a way to timeout Open3 processes without using signals or OS-specific modules.
Tested with Perl 5.8.0 under Windows NT, Perl 5.8.5 under Cygwin, and Perl 5.8.4 under Linux.
use IPC::Open3;
use strict;
my $timeout = 5;
my ( $wtr, $rdr, $err );
my $test_program;
if ( $^O =~ /win32/i )
{
$test_program = q{" $|=1; for( 0 .. 10 ) { print \"$_\n\"; sle
+ep 1; } "};
}
else
{
$test_program = q{ $|=1; for( 0 .. 10 ) { print "$_\n"; sleep
+1; } };
}
my $pid = open3($wtr, $rdr, $err, 'perl', '-e', $test_program );
my $forked = fork();
die "fork() failed: $!" unless defined $forked;
if ( $forked == 0 )
{
sleep $timeout;
kill(9, $pid);
exit;
}
while ( <$rdr> )
{
print $_;
sleep 1;
}
print "finished\n";

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).
