a few bk hints (was Re: [Xen-devel] segfault in dom0)

A bit offtopic, but maybe this will help somebody:

"bk changes -r+" is a more concise equivalent... but as Jody points out,
you can just "bk changes -r40f41ae00utn5d2f3tlNLcvG_QhiBA" to find out
what changeset that is.

That's perfectly true.  In fact that cset has a different version
number in my local tree than it does in Jody's output.  MD5KEYs and KEYs
are eternal, everything else is temporary.  (Well, I suppose the
contents are also eternal.  But comments and revision numbers, in
particular, are mutable.)

And on a slightly more xen-related topic:

Hmm, looks like your free(1) has -m as the default... I've always seen
-k as the default.

Or else you got it to boot with 11 pages of memory, which would be
quite a feat.
