     (Yes, it seemed close enough that I spent several hours debugging,
trying to get it the rest of the way. I ran out of time, so I wrote a
wrapper C library around the one I wanted to use, with threaded C
callback functions that signalled Smalltalk semaphores on which my
synchronous-FFI Smalltalk process waited. A hack, but it worked fine and
was simple.)
