There was a report on -current a while ago that a preliminary patch
to fix the non-threadsafeness of mmap(2) MAP_FIXED also makes flash9 work,
a fix for that seems to have been committed (kib 2007-08-20) and also
mfc'd to RELENG_6 by now (kib 2007-09-09), so, can anyone running either
verify that flash9 still crashes for them?

 Just wondering...
