Can you please be specific?  Last week you said you would have feedback
for me in a day, and it has been over a week.

I've not found any bugs in the LMDB patch set.  It has not changed
since the re-order you requested last week. 

What I have done is address yet another serious locking bug.  Indeed
rare but existing locking bugs have taken up most of the time for this
project!

Perhaps it happens more often with this patch, or perhaps it is just
like the branch point before Samba 4.8 where flapping tests came out of
nowhere.  Either way, what I've done is find and fix it.

(Gary did his due testing the entire time he was testing, and when he
first proposed it, and they didn't fail then).

I really, really don't want to leave this any longer.  I've got a set
of patches that pass the Gitlab CI.  They also show good results on
Catalyst Cloud autobuilds, results being:

lmdb-pre-7:
 - 2 success
 - nt4_dc notify

abartlet-lmdb-reordered-2:
 - 3 success
 - samba4.rpc.altercontext on ncalrpc with seal,padcheck.altercontext

dsheuristics-userpassword:
 - 2 success

I've got 7 more builds of abartlet-lmdb-reordered-2 running now to be
sure.  Once I get those back, I really want to land this.

For a number of reasons, I can't keep ploughing time into this.

That said, I realise you have put this aside into the 'don't need to
look at right now' category, but I've addressed the concerns you raised
and I do think anything else can be done after it lands in master.

All I'm asking is that you allow me to get review from other team
members.

Thanks,

Andrew Bartlett
