I mean that one should write the code having in mind that more than one
thread can share the same globals. For instance, I was working on twiki
(twiki.sourceforge.net) trying to make it work under mod_perl. In the
original implementation it had a lot of globals. This clearly lead to
mixing data of different sessions, so I put them in a private %config
hash (or, equivalently, in an object, created for each session).

A discussion about a cache module can be found in the Template Toolkit
(www.tt2.org) mailing list (maybe Randal is involved, too).

Is there any advantage in deferring images to visualizaton instead of
generation of the body? maybe the cleaning of cache similar to what
happens with kpathsea?
