Now runs a complete set of tests, notably including the AIO test.
File descriptors are passed in and out as plain ints (instead of
*os.File) for a couple of reasons: (1) We have to pass the plain int
to syscall.Select. (2) Turning an fd into an os.File causes golang to
set the blocking flag which is deeply unhelpful.
FWIW, using non-blocking FDs and syscall.Select is not normal best
practice for Go, where the expected model would be to use goroutines
with the file in blocking mode.
