It's the most up to date version on the tracker. Don't forget that
Thomas has been away a few weeks for exams.
It's also interestingly not the patch that he wants to commit now.

I think you misunderstood the discussion.
Details aren't entirely final yet, but the move callback will be allowed to
refuse moving. If actual implementation shows that for some cases this
is *too* awkward and locking functions would be better, the scheme might
be changed and such locking functions *might* be used introduced
The "copy" discussion last night was about a case where the data to save
is small enough to fit on the stack, which means that copy/save is just
easier for that particular case. If you re-read the logs, you'll see
that there was also a discussion about how things would be implemented
for dircache (including a proposed patch, although I think one really
needs to understand dircache to review that one), which would handle the
situation by refusing to move during crititcal periods.

by definition, not smart enough to debug it." - Brian W. Kernighan
