Nice! The problem with event loops is that a system should have only one.
Is there a thing like "async-check-and-do" that will do stuff or not block,
that could get polled as part of an existing event loop?

A quick search yields https://metacpan.org/dist/POE-Component-EasyDBI for
discussion; POE wants to be the standard event loop services provider.

I'm old-school and still write loops around select(2), which allows async
comms with separate processes using a little language over a pipe,
robustly, but that's no way to define a standard interface unless the
facility gets wrapped somehow. The tradeoff of only polling after the
select times out would be acceptable, I think, although it wouldn't be as
responsive as including the protobuf system's file descriptors in the
select set.

I don't know if there is a standard for mapping a FD number to a
[on-readable, on-writable, on-error] coderef triple, aside from just doing
that with an AoA, but were I wanting to integrate an async system into an
existing select loop, I could work with that. Especially if the system
offered to take the same shape of data as an input for its own select
loop.POE might have a standard for such things, I don't know.
