My thought here is that we want interruptible FFI code to be able
to say when it’s entering critical sections in a platform independent
way, and if it uses pthread functions to this effect, it is then tied
to POSIX.  Something more portable would be for the program to tie
itself to our OS threading library OSThreads.c
