Some of use are using OneShot for development. This launches the app server
every time so everything is fresh. This is a little bit slow and will only
get worse in the future.
I'm wondering if we can make a "refresh mode" for the app server, where
before each request is served, any modified modules are reloaded and the
CacheInstances/Classes settings are effectively 0. That would obviously
cause some delay, but probably far less than OneShot.
