	This problem looks to be one of the known locking issues with
bonding.

	Andy Gospodarek <andy@xxxxxxxxxxxxx> and I have been working
offline on the locking issues in bonding over the last several weeks.
At the moment, we have a generally stable (but ugly with debug fluff and
other yuckies) patch that seems to resolve at least the majority of the
various issues.  I'm thinking to clean it up for general posting early
next week, and address additional problems from there (since it's
hopefully at least a big step forward).
