	-u fails at this point, with a threaded build, for one of
	these reasons.

	* The kernel is to old to support capabilities.
	* The kernel does not have the capabilities module loaded.
	* You have disabled capabilities at build time.
	* PR_SET_KEEPCAPS is not supported.

	Linux's threads are broken.  You cannot call setuid() once
	you are multithreaded.  Named uses Linux's capabilities to
	work around this by keeping the ability to bind to reserved
	sockets after the setuid() call.
