--- Comment #48 from Torvald Riegel <triegel at redhat dot com> ---
The problem here is that the Austin Group has clarified that POSIX requires
stronger ordering guarantees wrt. waiters vs. signals than what the current
implementation offers. We can implement them, but we're not aware of an
(efficient) implementation that fulfills both these clarified POSIX
requirements and can do PI under all circumstances:

If you have further input on these choices, please comment on libc-alpha.
