Interesting - I was not aware of the dl() function for PHP. Of course, it would be disabled by any halfway competent administrator (because safe_mode would be enabled, which cannot be overridden by a user).
I haven't tried it, but with mod_perl a user ought to be able to modify his/her virtual host document root and mess with other users' stuff (it could modify anything dynamically generated). A user might be able to bypass bandwidth throttling too (although that could be fixed with proxy servers). What else... Would it be impossible for a mod_perl script to persist in the apache child and monitor information passing to and from the sites of other users?
The bottom line is, PHP is designed to be friendly to administrators. Mod_perl is designed to do anything and isn't appropriately sandboxed for shared environments.

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).
