This thinking is exactly what makes me scream loudly and run in the
other direction. I don't want threads introduced into the backend,
whether "gently" or otherwise. The portability and reliability hits
that we'll take are too daunting. Threads that invoke user-defined
code (as anything involved with datatype-specific operations must)
are especially fearsome, as there is precisely 0 chance of that code
being thread-safe.
