I've updated the FAQ entry a bit.

Thanks for the information.

As you can see from LockServer() function in 
http://cgit.freedesktop.org/xorg/xserver/tree/os/utils.c, the sequence of
actions should be

open(tmp)
write()
close()
link(tmp,lock)
unlink(tmp)

and the failure seems to be that the link() doesn't succeed.  So having the 
file "delete-on-close" does explain what is seen.

Any insight into why "delete-on-close" is being requested?
