I'm inclined to think that we should have a better understanding
of what is going on in the DB routines in this parent/child
situation. If it was something that worked in 4.2 but would
be newly broken in 4.3, then I would be more inclined to see
a last-minute sub-optimal fix rushed into 4.3, but as it is
I do not have a warm fuzzy feeling that the real problem is
understood at this point.
If someone familiar with these DB routines could look into
Dave's problem and comment, that would make any patch feel
somewhat warmer and fuzzier... Perhaps Dave should put up
a proposed patch to the gang in freebsd-audit as well as
freebsd-hackers?
