If I stop Thread.main, calling Thread.main.run in a signal handler does not wake up the main thread.

Please see this gist with a simple reproducible example:

trap handler (registered block) run on main thread. So Thread#run for main thread doesn't work.

You should use other ways to communicate trap handler and main thread, for example, Queue.

$q = Queue.new
trap(:INT){$q.push nil}

...
$q.pop # wait for trap handler
