A clear and concise description of the bug:

Recent build: https://buildbot.python.org/all/#/builders/1050/builds/2826

Dictionary watcher tests using catch_unraisable_exception context manager fails on the "wasm32-emscripten node (pthreads) 3.x" buildbot: the exception was logged too late, after catch_unraisable_exception block.

Example of error:

test_dealloc_watcher_raises_error (test.test_capi.test_watchers.TestFuncWatchers.test_dealloc_watcher_raises_error) ... Warning -- Unraisable exception
Exception ignored in: 'PyFunction_EVENT_DESTROY watcher callback for <function loop at 0x19e62a0>'
Traceback (most recent call last):

    raise MyError("testing 123")
test.test_capi.test_watchers.TestFuncWatchers.test_dealloc_watcher_raises_error.<locals>.MyError: testing 123
