which is why it hasn't been done yet. ;)

I guess that's the first question to ask: what concurrency is possible
or desired in nano-X?

I was thinking posix threads since they seem to be supported in both
Linux and RTOS worlds...
at the very least it would be nice to have a hook for a global lock
callback. currently I'm having to play linker tricks (--wrap GrFOO) to
wedge this in. separating into client-server is a possibility, but
that's a separate can of worms when dealing with what is effectively a
multi-threaded single process. :)
