This buffering introduces the same potential risk of the
"stdin-feeder" process not being able to see objects right away as my
version had. I'm planning to mitigate the issue by unplugging the bulk
checkin when issuing a verbose report so that anyone who's using that
output to synchronize can still see what they're expecting.

I think the code you've presented here is a lot of diff to accomplish
the same thing that my series does, where this specific update-index
caller has been roto-tilled to provide the needed
begin/end-transaction points.  And I think there will be a lot of
complexity in supporting the same hints for command-line additions
(which is roughly equivalent to the git-add workflow). Every caller
that wants batch treatment will have to either implement a state
machine or implement a buffering mechanism in order to figure out the
begin-end points. Having a separate plug/unplug call eliminates this
complexity on each caller.

Btw, I'm planning in a future series to reduce the system calls
involved in renaming a file by taking advantage of the renameat2
system call and equivalents on other platforms.  There's a pretty
strong motivation to do that on Windows.

Thanks for the concrete code,
-Neeraj
