Do we have a consensus on what platforms and conditions the swap problem
exists? Any such info is GREATLY needed. I can only assume it really
exists on ALL platforms at this point.

Here's the big favour: Is anyone with a stable/fast machine able to tarball
up a complete build of the lastest cvs with this file (both source and obj)
and make it available to me for FTP? I really don't think I need mention
the speed of the uvII here, and the fact that I'm manually traversion the
first directory levels from the TLD to hand-hold a build through to
completion here ;) I'd REALLY appreciate this head-start.
