A cross-platform test might be hard to write.  So far I've used
- running a threaded call to system(1, i.e. unix) with some argument like
sleep 60 while forking a loop that counts and printing the count afterward.
 if the count is small the call blocked
- calling a complex Mac OS X native file dialog with callbacks for the
filename filter and the accept and cancel actions
- making non-blocking calls on a MySQL db through ODBC
- (and my favourite) running an image that forks a reader that loops writing
a squeak> prompt, reading from stdin and evaluating the chunk.

Of course the last, while fun to use (one can interact with the image
concurrent with using the reader) isn't that easy to adapt to an automated
test.

One of the nest tests is to create an OS semaphore and then fork a threaded
call to wait on it, wait on a delay and then signal the semaphore with
another threaded call.  Tests can be built up upon this basic approach.
 i.e. we need to write appropriate automated tests of the threaded FFI.
