For what I see from the 2483 time-sliderd truss output, it does the
following for each /etc/X11/fontpath.d/*/ directory:

1) with a convoluted procedure, produce a lock file .uuid inside
    that directory

2) Then use utimensat to update access and modification times of
    that directory   *********

3) Open RDONLY  *.cache-n file in /var/cache/fontconfig/
             /export/home/predrag_zecevic/.cache/fontconfig/
             /export/home/predrag_zecevic/.fontconfig/
    (there are none)

4) Do the same RDWR (there are still none)

5) fstat all .pcf files and fonts.dir and files mentioned therein
    in the fontpath.d dir and mmap them

6) do something (not seen in truss) and unmap them

7) remove the .uuid file

8) repeat from 1)

Could it be that the change of the modification time (2) from 2483
triggers the reread by 2484 (mate-settings-daemon) ?

And by the way, if I counted correctly, this system has over 24.000
individual fonts, so the caching procedure a) really takes a while,
and b) makes no sense at all since almost all of them are obviously
unused. And indeed, the 2484 truss shows no loop up to the truncation
point, these are all different fonts...
