Subject: OTP-8342  Processes, and/or ports could get stuck on a blocked
 scheduler           when erlang:system_flag(multi_scheduling, block) was
 used.

          Processes, and/or ports could get stuck on an offline scheduler
          when schedulers online were reduced using
          erlang:system_flag(schedulers_online, SchedulersOnline).
