Such a patch would also address issues that SGI has with exporting mappings via XPMEM. Plus a variety of other uses. Go ahead and lets do more in this area.

That may also become possible with some of the work that we have in progress and that also requires a patch like this. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
