In addition to the notes for SVR4.0, you need to be aware of a few
problems with SVR4.2. Basically, the base SVR4.2 code has broken
Unix-domain sockets in such a way that making local connections via
UNIXCONN does not work properly (this bug is known to exist
on Consensys
SVR4.2 and Novell UnixWare). The manifestation of this bug is that
windows remain on the screen after the client program exits, until you
move the mouse into the window, or otherwise cause the server to try to
write to the client.
If you run XFree86 and see the manifestation of the Unix-domain socket bug
described above, you can work around this problem quickly and effectively
by changing the default local connection mode to NAMED rather
than UNIX.
The mechanisms for doing this are described above. This is not a problem
for clients using the X11R6 X libraries because UNIX is no longer
considered a local connection type.
