Subject: [PATCH] Mask ctlc borked REPL tests
Namely the `tractor.pause_from_sync()` examples using both bg threads
and `asyncio` which seem to go into bad states where SIGINT is ignored..
Deats,
- add `maybe_expect_timeout()` cm to ensure the EOF hangs get
`.xfail()`ed instead.
- @pytest.mark.ctlcs_bish` `test_pause_from_sync` and don't expect the
greenback prompt msg.
- also mark `test_sync_pause_from_aio_task`.
