We got a report about Maxima calling stat on a lot
of files when the program is launched.
Aside from all the files in the Maxima share directory,
which we expect Maxima to look at, stat was called
on a lot of other files as well (stuff outside the Maxima
directory structure).

An unfortunate mistake: DIRECTORY used stat() on all entries in a directory, not only those that matched the mask. It was just a matter of switching lines. Now things are better. Thanks a lot for reporting.
