Please note that the FD-client and fd-client test programs will fail
horribly and freeze your machine if you run them on certain versions
of SunOS 5.2.  Apparently there is a bug in SunOS 5.2 that is
triggered when passing file descriptors between separate processes.
This bug has been reported to Sun and is fixed in the later 5.2
patches (and hopefully also in 5.3).
