Use our `._post_mortem` from `open_crash_handler()` 

Since it seems that `pdbp.xpm()` can sometimes lose the up-stack
traceback info/frames? Not sure why but ours seems to work just fine
from a `asyncio`-handler in `modden`'s use of `i3ipc` B)

Also call `DebugStatus.shield_sigint()` from `pause_from_sync()` in the
infected-`asyncio` case to get the same shielding behaviour as in all
other usage!
