hm, another X15 caching artifact i noticed: i've changed the index.html
file, and while X15 was still serving the old copy, TUX served the new
file immediately.

its cache is apparently not coherent with actual VFS contents. (ie. it's a
read-once cache apparently?) TUX has some (occasionally significant)
overhead due to non-cached VFS-lookups.
