It is not an easy problem in the general case
I implemented in C a system with time-out and a command
ish wich I use in production. It has one limitation and there is a trick: I use setpgid() in the father and the child (you need both to avoid a race condition),
this way I can kill(pgid), which actually kills everything
the exec()ed process starts ...except if it itself uses setpgid() like daemons (this is the limitation ;)</>
using the POSIX module, I think a pure perl solution is not too complicated (a line by line translation, but hey if it works...) if you want the code contact me at

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).

or How to display code and escape characters
are good places to start.
