server reload responsiveness

["stefan@eissing.org" <st...@eissing.org>]

I really like the amazing improvement by Yann to keep 
the server responding during reloads! Well done!

What I wonder, hoping that we are able to backport it, 
how this could affect productions. I know from feedback
on h2 that some systems have memory pressure during
reloads and whished for h2 workers to close down asap
on a graceful.

Won't such system not also be affected by the new
behaviour? Do we need to provide a way to opt out
of this?

Cheers,
Stefan
