Thanks for the info. It'd be great to figure out where/why this is
going wrong. As I said, it used to be the default case under
autotools, and I don't think we had a problem with it. If it's a new
feature in OSX version x.y.z, then we'll have to live with it until we
can figure out a workaround.

If no one can figure out how to get shared memory mapping to work,
we'll add another check to disable it for both Windows and OSX.

Thanks,
Tom
