In case my previous e-mail sounded too enthusiastic, I'm also pensive
about this direction.  I'm not sure I'm ready to totally give up on
all of Linux WSI just yet.  We definitely want to head towards memory
fences and direct submission but I'm not convinced that throwing out
all of interop is necessary.  It's certainly a very big hammer and we
should try to figure out something less destructive, if that's
possible.  (I don't know for sure that it is.)
