I'm reminded of how much I despise sysvr4 STREAMS ... they obscure so much
useful stuff under abstractions. This is *probably* an accept()
call.

This is select() implemented as poll() under the covers.

This is the parent.

Look at all that fun stuff! How ugly. What is it smoking with that
fcntl() call? Interesting.
Ok, wild guess time, try adding -DUSE_FCNTL_SERIALIZED_ACCEPT to
EXTRA_CFLAGS in Configure and rebuilding the entire server. I'm
guessing unixware doesn't like having the same socket inside an
accept() and a select() at the same time.
