No problem.

As long as you have cygserver started and CYGWIN=server defined in a way 
that XWin can see it from however you are starting it, then you should 
*not* see the following around line 40 in /tmp/XWin.log:

========================================================================
MIT-SHM extension disabled due to lack of kernel support
XFree86-Bigfont extension local-client optimization disabled due to lack 
of shared memory support in the kernel
========================================================================

If those lines are missing then shared memory is being used.  There is 
no positive indication in the log that shared memory is being used, just 
the absence of the negative indication.

Hope that helps,
