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.
