Some of which I can address, I think.  Thanks for your comments.

It's possible I could do this with a little research into how to 
delete a map from memory.  I could simply call the reset function
on each style map when I leave the style function.  I wasn't
worried about memory/disk space....  These suckers are usually
small.

I think I have fixed this:  the only writing which was being done
in the LIBDIR was done by me trying to open the output file for
writing.  In the server, I never actually SAVE the map:  I only do
that in the standalone version.  So what I saw was zero-length files
getting created.

I fixed this up so it shouldn't write anything in the /random dir.
It just needs to exist, I think.

I think that's how it works now, in my own personal version of the
code which I'll give to you to evaluate in a little while (this week
sometime).

I'm interested in the answer to this:  disposing of the maps is
a good idea.

Raphael, I still can't repeat your weird problems with maps.
