Let's tweak what we do if we detect a flood of requests to start more workers: if none of the workers ever sticks (i.e. the worker count is zero) then let's just give up, as before. Otherwise, let's just not start more workers for a while, and do so again after a while. Thus spawning ofr workers will "cool off" for a while. Fixes: #27028
