Because of a bug.  If a program such as GNUemacs does an ioctl() to the
u-domain socket which the socket code doesn't support, it can cause the
kernel to panic.  Our product-version libX11.a traps these bogus ioctl()
calls, and future versions of the HP-UX kernel will not exhibit this
unfortunate behavior.
