It crashes without the printNl, it needs the call to delay wait. I can create
the Delay for each process once and it is still crashing, it also needs a lot
of processes to force this crash. It crashes within 30 seconds or such.

I am going to try your approach with GDB, watchpoints and continuing a couple
of times and see if I can get it to crash and have gdb right there. I might
also try reverse debugging...
