[FR] Make inline eval responsive during "indexing packages"

[marius311]

Not sure if this is a regression or not (I don't remember the old behavior tbh, I have a very vague but possibly wrong feeling this is new) but with Julia 1.6 / julia-vscode 1.1.25, inline evaluation is frozen while "indexing packages". It would be great if the indexing could happen in the background instead.

I also have a feeling this is a regression. Inline evaluation is frozen on startup for a while even after "indexing packages" is no longer showing, and sometimes freezes for a few seconds later on as well.

Pretty sure the "indexing packages" stuff is mostly a red herring and there's another performance issue in the LS that blocks it for other requests.

[marius311]

That makes sense. Consider this as my report that "LS is definitely blocked at least during indexing" not that "indexing is causing the block".

This would be extremely useful! With 1.6, this behaves in a more determinstic way than before, but the blocking nature is a major issue in my workflow (as a noob, I'm adding libraries on the go...)
