Revision 16b34aa44b257155d9392a19e08e4ce139bc2789 authored by Ronnie Sahlberg on 08 March 2019, 02:58:21 UTC, committed by Steve French on 15 March 2019, 00:32:35 UTC
Reserve the last MAX_COMPOUND credits for any request asking for >1 credit.
This is to prevent future compound requests from becoming starved while waiting
for potentially many requests is there is a large number of concurrent
singe-credit requests.

However, we need to protect from servers that are very slow to hand out
new credits on new sessions so we only do this IFF there are 2*MAX_COMPOUND
(arbitrary) credits already in flight.
