It worked in the reduced testcase with sem_wait(). With read() itâs
still half-broken. See below.

Asynchronous cancel seems to work as well as deferred cancel now. Thanks.
Both cancel types work with sem_wait() and pause() now, but for threads
blocked in read() theyâre still unreliable. Only one of three blocked
threads is killed in the attached updated testcases.

Okay, Iâll hope for him to respond then.
