Re: How to call runForever()?

[monster]

OK, I've got it! It has _nothing_ to do with runForever() or asyncdispatch.

Here another example that crashes:
    
    
    import os
    
    proc whatever() {.thread, nimcall.} =
      echo("TEST")
    
    proc initProcessX(): void =
      echo("In initProcess()")
      var thread: Thread[void]
      createThread(thread, whatever)
      echo("initProcess() done")
    
    proc doStuff(): void =
      echo("In doStuff()")
      # ...
      initProcessX()
      sleep(500)
      # ...
      echo("Crashes before getting here!")
    
    doStuff()
    

And here, one that doesn't crash:
    
    
    import os
    
    var thread: Thread[void]
    
    proc whatever() {.thread, nimcall.} =
      echo("TEST")
    
    proc initProcessX(): void =
      echo("In initProcess()")
      #var thread: Thread[void]
      createThread(thread, whatever)
      echo("initProcess() done")
    
    proc doStuff(): void =
      echo("In doStuff()")
      # ...
      initProcessX()
      sleep(500)
      # ...
      echo("Crashes before getting here!")
    
    doStuff()
    

It looks like the issue is that I don't have a "hard reference" to the thread 
itself, so I assume it gets garbage-collected. Should I always keep a 
hard-reference to threads, until they are done? Or is that a bug?

EDIT: My "real" code is still crashing after the fix I discovered, but now I'm 
getting a stack-trace, so I think I should eventually work it out too:
