[issue21009] Potential deadlock in concurrent futures when garbage collection occurs during Queue.get

[Mark Dickinson]

Mark Dickinson added the comment:

Adding Brian Quinlan to the nosy list.

I don't see an easy way around this other than documenting it and recommending that people do explicit executor shutdown where necessary.

Weakref callbacks are dangerous things.  Weakref callbacks that acquire a lock at any point doubly so.

nosy: +bquinlan
