Heh, I was just thinking about a cache myself... :-)  Perhaps we
could add a cache= option to pagelist, which allows an author to
specify a name under which the resulting output is to be cached.
(The cache is then invalidated by any page update.)

One of the problems with a cache is that it's mutually exclusive
with $EnablePageListProtect, unless we assume that read-protected
pages will never appear in the output (even if the person is
authorized to read them), or don't cache any results that have
read-protected pages.

Indeed, this is the generic problem with any sort of caching in
PmWiki -- pages can be dynamic depending on the identity of the
visitor.  I keep brainstorming ideas about good ways to achieve
caching, but so far nothing great has appeared.  

On a related note, I'm really desirous of having a standard directory
(other than wiki.d/ itself, although it could be a subdirectory of
wiki.d/) where cache files, index files, and other working files
could be safely kept.
