Thanks for responding Jason.  I'm curious: are these patches in use at Apple
not considered suitable for submission to the FSF?  I'm just wondering why
you maintain a separate tree rather than pushing everything out.  We're
trying hard to get all our changes rolled in to avoid the hassle of having a
separate tree.

cheers,
