I knew this. When I heard that reloads wouldn't block queries, I assumed
an implementation something like:
Fork a new process
Child process continues to service requests (using old data)
Parent process reloads
When parent is finished reloading, it kills child and services requests
However, now that I think about it, there could be problems with this
scheme if dynamic updates are received during the reload -- they'll be
processed by the child, but when the parent finishes reloading it won't
know about those changes.
