semaphore: Teach semThreadWait to use semWait with threaded RTS · 39c330c5

Bodigrim committed 2 years ago

semThreadWait uses a rather atrocious polling loop to avoid
blocking, which we block the entire program when using the non-threaded
runtime. However, this is unnecessary in the threaded runtime, where we
can instead simply block in semWait. Take advantage of this.

Fixes #253.
