I run much the same configuration and it works fine for me -- no
shared memory problems.  However, I am a bit behind the latest Cygwin
DLL release.

In the past I've seen symptoms similar to what you report, but they
went away and I'm not sure which of the many changes I made to my
system made the difference.  This may be superstition, but one thing
that seemed to help at least once was to clean up the temp files used
by cygipc:

+ stop the Cygwin ipc-daemon service and (before that) any services
  that depend on it.
+ remove all the /tmp/MultiFile* and /tmp/cygipc* files.
+ start up the services again.

WARNING: Run this procedure at your own risk.  I can't guarantee that
it won't mess up your system.
