As it stands right now, when a Red Hat font package is installed, 
chkfontpath is called to add it to the xfs font path.  The last 
thing chkfontpath does, is check and see if xfs is currently 
running, and if it is, it sends a SIGUSR1 to the xfs process, 
which causes xfs to reread it's config file.  This will add fonts 
to be useable right away, however there are some cases in which 
it will not work if I understand correctly, however it is a 
convenience nonetheless.  For fontconfig, the fonts are useable 
immediately in some applications I believe, while other apps 
require a restart.

xfs is not signalled to reread it's config file upon font 
uninstallation, however IIRC, that causes problems anyway 
although I don't remember what they are.  I believe it has 
something to do with glyph caching or somesuch.  Maybe Owen 
remembers more than I do... it's even possible the problems I 
seem to recall don't exist anymore...
