someone told me some time ago that setting ulimit -n <number> sets the 
maximum connections for X11 to roucghly the number. What about changing the 
startup scripts to set the default to eg. 512? 

I don't like the idea of changing dynamic configuration to a static one.

Of cause we should put an entry into the FAQ too.

A1. Run netstat and count the connections to local port 6000.
    netstat | grep " *TCP *[^:]*:6000" | wc --lines
    will give you an count of the connections to the xserver. The number
    of open files may be larger, but not too much.

A2. Set the maximum number of open files for a program to a higher value.
    Run "ulimit -n 1024" from a bash und start XWin from this bash.
    This will set the maximum number of open connections to 1024.

HTH, bye
