I'm at a loss re: how to make tokio happy across shared object boundaries. Yes there's N copies of tokio's code, now I can't share them because different monomorphizations = missing symbols (the cargo-add-dynamic trick doesn't work with my "cdylib plugins" approach).
Handle::enter across SOs panics. Handle::spawn panics. I thought "mostly" tokio::spawn needed a "current runtime", but "Sleep::new" does too, duh.
I foresee lots of debugging in my future.. god that's a lot of debugging.
