Subject: Re: X protocol question (I solved my problem).

It turned out that for some reason I was not getting SIGIO's on the
sockets, and I was using that to determine whether to read off of the
X socket.
The fact that this would cause the X server to crash is another
problem...
[Senario was:
program listening at 6001 and X1
and with a io channel to another machine with a real X server
at X0/6000
on other machine, program listening on the io channel, and
when it recieves a new connection connecting to Real X and X0
I had done the usual for SIGIO's (fcntl setown, flags = FASYNC,
handler for SIGIO's....)
but the process which open'd the socket to the Real X server
never got one, and then the X server would die often a few
minutes after I had killed all of the processes.]
So, I changed the code not to need SIGIO's
