--- Comment #4 from Nick Fitzgerald [:fitzgen] [⏰PDT; UTC-7] <nfitzgerald at mozilla dot com> ---
Apologies. My attached testcase's behavior was due to not compiling with
`-pthread`.
Unfortunately, I have not been able to reproduce the futex syscalls with a
timeout in the past that would wake constantly and then immediately make
another futex call with a timeout still in the past, etc etc.
If I can reproduce, I will reopen or file a new bug.
