we generally do not want to catch or throw these. catching them to print and discard is fine, tests are largely exempt, and cases in which we can be certain where the exception came from are also fine to *catch*. we'll try to never *throw* (or rethrow) these if possible though because doing so will make it impossible to construct async traces for the exceptions.
