Sorry replying to myself, but just after I sent the message I figured
it isn't possible.
The tss must have a unique identifier that is equal throughout all threads.
It should be possible to use the tss address as a key to some sort of
map/hash, where it would contain the value. It wouldn't be O(1), but
having it growing unbounded is IMO, worse. At least for my use case.
