Subject: robust list not issuing FUTEX_WAKE

Hey Musl Folks,

I'm trying to understand the futex robust list and it's not quite working
how I would expect it to from a reading of the man pages.

In a minimal example, I'm getting the futex changed to FUTEX_OWNER_DIED
instead of FUTEX_OWNER_DIED|tid and I'm not getting a FUTEX_WAKE event.
Any idea why this might be?

Happy to share the minimal example.

Thanks for any help,
--Leo
