system() never returns, how to kill it?

[Zhidian Du]

I am writing a cgi program.
When I use system and it never returns. How can I kill it, for
example, after 5 seconds?

I searched the whole sites and cannot find it.

Thanks.

I tried using this method on Win32 but the system commnd still
executes as a background process and consumes resources. Is there any
way to kill it on Win32?

use Win32:rocess;

if(!($process->Wait($milliseconds)) {
$process->Kill();
}
else {# process has already terminated}

Cheers,
