But what if you want to listen to audio from a different application connected to Jack while exporting?

That's basically ridiculous.

Surely it should just disconnect from Jack (although this could possible cause routing issues on reconnecting once finished) and run as fast as possible using max CPU cycles.

You're ignoring the idea that export may involve other JACK clients. It may involve, for example, a JACK client functioning as a software synthesizer, or a JACK client function as an "outboard" FX processor. Disconnecting from JACK would be completely wrong in such cases, and special casing the examples where we *could* disconnect from JACK is an absurd amount of extra work given that we are using JACK's ability to drive the process cycle AND share data (even within Ardour itself.
