Given an RP2040 CPU with two ARM processors (we call them Alice and
Bob), how can they talk to one another?

We hate FIFOs. Is it possible for them to share a block of the SRAM?
It would be cool if the two programs could both declare a struct and
both be able to access it simultaneously. We's manage the access
details ourselves, who writes to what variables.
