The reports that I've heard say that very large amounts of shared memory
don't seem to offer performance improvements on Windows like you can get
on Unix, so there isn't much reason to put in the (large amount of) work
that would be needed to produce a native Win64 version.

The exact reasons why Windows doesn't like large shmem aren't clear,
at least not to me.
