#
# bUt wHy duZ It WorK lIKe dis..
# ------------------------------
# from the perspective of the `tractor.Context` this
# cancel request was conducted "out of band" since
# `Context.cancel()` was never called and thus the
# `._cancel_called: bool` was never set. Despite the
# remote `.canceller` being set to `pikerd` (i.e. the
# same `Actor.uid` of the raising service-mngr task) the
# service-task's ctx itself was never marked as having
# requested cancellation and thus still raises the ctxc
# bc it was unaware of any such request.
#
# How to make grokin these cases easier tho?
# ------------------------------------------
# Because `Portal.cancel_actor()` was called it requests
# "full-`Actor`-runtime-cancellation" of it's peer
# process which IS NOT THE SAME as a single inter-actor
# RPC task cancelling its local context with a remote
# peer `Task` in that same peer process.
#
# ?TODO? It might be better if we do one (or all) of the
# following:
#
# -[ ] at least set a special message for the
# `ContextCancelled` when raised locally by the
# unaware ctx task such that we check for the
# `.canceller` being *our `Actor`* and in the case
# where `Context._cancel_called == False` we specially
# note that this is likely an "out-of-band"
# runtime-cancel request triggered by some call to
# `Portal.cancel_actor()`, possibly even reporting the
# exact LOC of that caller by tracking it inside our
# portal-type?
