GC issue? List.pool overwritten by allocated object

Do those threads call back to D code that allocate from the GC? If so, 
the GC must be aware of the threads to be able to suspend them during a 
collection.

I had to call thread_attachThis() to do that in a past project:

   https://dlang.org/library/core/thread/osthread/thread_attach_this.html

However, it was not clear whether or when to make a corresponding call 
to thread_detachThis(). If Vulkan threads disappear on their own, your 
only chance for a call to thread_detachThis() may be right before 
returning from your D callback function.
