Well I got some good answers in the perl-gtk IRC channel.
11:59:09 <metaperl> i'm wondering about alternatives to threads for keeping a perl/gtk app responsive - http://perlmonks.org/index.pl?node_id=928823
12:03:31 <LotR> simple. don't do anything that takes more than a few microseconds :) and if you do, split it up in tiny pieces and stick those in an idle handler.
12:03:34 <LotR> also, see POE

12:46:43 <metaperl> oh sorry
12:46:46 <metaperl> for the repeat
12:46:52 <metaperl> My window was smushed down
12:47:20 <metaperl> lotr - what is an idle handler? is this documented somewhere?
12:49:21 <metaperl> this looks relevant - http://search.cpan.org/~rcaputo/POE-Loop-Gtk-1.305/lib/POE/Loop/Gtk.pm
13:09:56 <squentin> metaperl: Glib::Idle->add(\&my_function) see http://gtk2-perl.sourceforge.net/doc/pod/Glib/MainLoop.html

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
