Topic: wasmtime / PR #5858 wasi-threads: fix use of `wait` in test

Wasmtime GitHub notifications bot (Feb 23 2023 at 00:08):

abrown opened PR #5858 from fix-threads-test to main:

As @yamt points out [here], the wait/notify pairing used in this manual WAT test was not effective. The wait always immediately returned, meaning that the main thread essentially spins until a counter is atomically incremented. This is fine for test correctness, but was not the original intent, which was lost in a refactoring. This change uses the $i local to keep track of the counter value we expect to see for the wait, so that the wait/notify pair actually waits as expected.
