 assume that time never jumps backward.  See trac #1525 for previous
 symptoms of this fundamental problem.

 Valid. The solution to bug #1525 worked around this by enabling fontconfig
 to write a cache in $HOME/.fontconfig and move ahead with that (previous
 to bug #1525, fontconfig could not write cache files ''at all'' if the
 system time was backwards compared to the timestamps). However, for newer
 versions of our releases, it seems that fontconfig cannot write to
 $HOME/.fontconfig (I have not confirmed this yet - but this is what the
 comments seem to indicate).

 Mozilla pre-caches the set of available fonts at startup, and uses
 FcConfigUptoDate() to figure out if new fonts have been added to the
 system
 (http://lists.freedesktop.org/archives/fontconfig/2004-July/000960.html).
 And the only straightforward way for fontconfig to know if there are new
 fonts in the system is to check the timestamps of the directories which
 contain the font files, and to compare it with the timestamp when the
 FcConfig was initialized by the application concerned.

 Is there any way that the security system can allow applications to write
 to .fontconfig ?
