1. Issues regarding caching:  The ESP32 has no D-Cache and thus the
   issues described there do not apply.
2. Issue regarding assertion: No chip does this at the moment.

1. Cache Issues. I have not thought about this yet, but certainly caching is
an issue in an SMP system:
- Cache coherency. Are there separate caches for each CPU? Or a single
shared cache? If the are separate then keep the caches coherent will
be an issue.
- Caching MAY interfere with spinlocks as they are currently implemented.
Waiting on a cached copy of the spinlock may result in a hang or a
failure to wait.
2. Assertions. On a fatal assertions, other CPUs need to be stopped.
