- Pre-fork 'processes.spare' application processes;
- fork more processes to keep 'processes.spare' idle processes;
- fork on-demand up to 'processes.max' count;
- scale down idle application processes above 'processes.spare' after
'processes.idle_timeout';
- number of concurrently started application processes also limited by
'processes.spare' (or 1, if spare is 0).
New optional configuration parameter introduced: limits.reschedule_timeout.
Default value 1 second. In the case when request is written to the port
socket 'in advance', it is called 'pending'.
On every completed request, the head of pending request is checked against
reschedule timeout. If this request waiting for execution longer than
timeout, it is cancelled, new port selected for this request.
