Looks good to me too.  Is it possible to devise an easy test case in
shell?  Asking because esp. the parallel Autotest code fiddles a lot
more with file descriptors so it would be nice to know we don't regress.
(I can look into writing a test case eventually.)

Luke, can you try out your testsuite with -j3 passed to it (in
TESTSUITEFLAGS if you call it through the documented makefile snippet)?

Thanks,
Ralf
