Thanks for the feedback, that looks like it could be the right way to go
about it!

However, I'm a bit unlucky because my application is implemented as
dynamically loaded modules attached to another application, which there is
a large warning about in your link. Do you know of any additional more
detailed information about how best to ensure the data lifetimes are
managed correctly so async sinks don't crash when modules are loaded or
unloaded?

Cheers!
