Subject: erts: Patch 1113

    OTP-8475  Driver threads, such as async threads, using port data locks
              peeked at the port status field without proper locking when
              looking up the driver queue.

    OTP-8487  A call to the BIF unregister(RegName) when a port had the
              name RegName registered in the runtime system without SMP
              support caused a runtime system crash. (Thanks to Per Hedeland
              for the bugfix and test case.)

    OTP-8591  Fix memory management bug causing crash of non-SMP emulator
              with async threads enabled. The bug did first appear in
              R13B03.
