On gunicorn reload, extend allocated xseg pool per worker class array until the already spawned workers exit. On a graceful worker exit the previously allocated xseg pool is properly shutdown and the new workers takeover the next series of xseg ports. On a next reload basis the new workers will always take over the previously allocated xseg pool ports. With this mechanism we always need at least twice the number of workers in xseg ports per pool. Care must be taken in xseg ports accounting and bookkeeping when we dynamically change the number of workers by using the TTIN and TTOUT signals sent to the master. The total number of xseg ports allocated by all workers must not exceed the minimum port being used by the Archipelago peers. If the total amount of used ports exceeds this limit one should rearrange the Archipelago peers ports along with the relevant dynamic port range.
