In general, synchronous events are bad from an architectural point of
view.  They result in large, complex callstacks, which expose crashes
and security vulnerabilities.  In the long term, they also impose
contraints on how tightly coupled different components need to be.  If
two components need to communicate synchronously, that limits our
future ability to modularize the platform and to exploit parallelism.
