I don't understand what you mean by "mistake" at all.  Yes the DPU
catalog portion of this series sat in my local branch for a very long
time.  Yes it had to be rebased on top of conflicts many many times.

However, that time has also been used to fix and extend DPU where
necessary, instead of submitting a half-broken or half-incomplete
catalog entry...

Re "we overstayed": you could have asked to clean up and send my patch,
so I don't take this as a mistake on my part as you are completely aware
of my time schedule ;)

Also here, don't forget to re-quote my message if you break half-way in
the line.
