Honza, could you please redirect this to someone who can take a look?
It looks to be high frequency, and only affects osx 11.

test_stepping-12.js wasn't correctly waiting for thread to be resumed between each of its sub test.

Similarly, other tests weren't waiting for thread front's resume request to be resume.
I'm also spreading the usage of resumeAndWaitForPause to better ensure we resume and wait for next paused event
without any race condition. Listening to "paused" after calling "resume" is subject to race conditions.
