Hmmm, I have no idea why I wrote this. According to the code for 
the runtime it only suspends threads that inherit from Thread? GC 
fullcollect calls thread_suspendAll which traverses a linked list 
of Threads.

So I suppose none of your threads are suspended unless you 
suspend it with Thread on call_back entry? But why suspend a 
@nogc thread?
