It can't; that's why it falls back to a per-user cache file to cover font
files not listed in the per-directory caches. The library contains the
code to write the per-directory caches so that a privledged task can
create them easily.

There's no call necessary to update the cache for future applications;
those will automatically discover the new file. The existing Xft library
doesn't have a mechanism to update the cache in a running application.

There is no current mechanism for this, and there are a couple of questions
to be answered before we can design one:
+ What basic signalling mechanism should be used
+ Who has permission to signal apps
Suggestions are welcome, as this would be a useful addition to the
architecture.
