From d5dca21a958001a555b9a313156567f0bdec643b Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Thu, 15 Jul 2021 11:48:48 -0600 Subject: lib/thread: Add thread_yield helper method This helper method is just a shorthand for `thread_yield_microseconds(0)`. I think it makes it clear that we want to yield a thread without delaying.
