Ok, sounds good.

Right, that's a mistake.

The while loop is simulated by repeated call to locateFontsStart()
without changing
state and parameters. In LOCATE_FONT_FIRST the parameters are set to false,false
and state to _VIRT. The next time locateFonts() is called from
locateFontsFinished()
if virtualFontsFound was not set to true then in remains in the same state.

Here the issue is that locateFonts is called repeatedly and it cannot
be used for initialization,
unless locateFonts() is split in two calls, one for initialization and
for external calling, the second
for switching states and being called internally. I might do this in
the next patch.

Another concern is that the changes may go higher in code because the
asynchronous
processing in locateFonts() may not return results in time for dvi
rendering. Do you know
a way to install a considerable amount of font files? I'd like to slow
down the processing
and see what happens.

I will try to provide the updated patch tonight.

Thanks for your patience :)
