And luck was not to be had.  Apparently 'git bisect skip' has some bad O(n**2)
issues - I tried to exclude the kvm.git tree, and it ended up running literally
overnight with no signs of stopping (see the gory details here:
https://bugzilla.redhat.com/show_bug.cgi?id=522599 )  Now, I probably *could*
cobble up something to do the skip as a series of little 20-40 commit skips,
but that's just getting nuts. ;)

Given that I'm having little luck bisecting this issue in linux-next and
we're now into the merge window, does anybody have a *better* idea than letting
the issue get into Linus's tree around -rc1, and hope that bisects more nicely
than linux-next did, so -rc2 has a fix for it?
