  While the modules are reloaded on HUP, so are the virtual servers.  So
you can put "unlang" into a file, and it will be reloaded on HUP.

  Yes, but it's not any faster than the "files" module.  There's no need
for "fastusers" any more.

  ... and many other features, which are in "unlang".  I'm wary of
re-implementing the same thing multiple times.

  It's probably simpler just to add case-insensitive regex matching to
the core.  That way *all* of the modules get the functionality, and not
just "users".
