Tried to do this a while ago and had the same fork/exec problem. It's possible to fork/exec and have the page load. Apache waits for the child process to close off its handles before loading. So you just have to close them manually:
if (!defined( my $child_pid = fork()))
{ die "Cannot Fork: $!" }
elsif ($child_pid)
{
print "</body></html>";
exit(0);
}
else
{
close(STDOUT);
close(STDERR);
close(STDIN);
exec("$my_command");
exit(0);
}
If you're planning on launching processes and don't really need a web interface, it's worth considering perl Tk. OK user interface, fewer security issues, and no quirks introduced by apache.

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).
