or you can do what we do with RTEMS and stick a lock around all the Gr*
functions to ensure that only one thread at a time is in nano-X. it is
not elegant or the best way to do things, but it does work. I can send
a makefile snippet and code to anybody who's interested.
microwin/nano-X is probably never going to be completely reentrant, but
at least it would be nice to have hooks in place for fine-grained data
locking. if I only I had the time. ;)
