Markus Schirp d8e6805206 Fix actor race condition
* Use the `ConditionVariable` primitive to fix rece between stopped
  receiver Thread and its wake signal.
* Race was only observable via synthetical benchmarks and explicit
  sleeps between unlocking receiver mutex and Thread.stop
* Simplifies code a lot as thread must not be passed around anymore
