Sorry, a little busy with the LSP plugin :-).
Yeah, "somebody" keeps raising issues on it (sorry) :-)
That's totally great.
By "busy" I actually meant "doing this new exciting thing and neglecting the old boring tag manager" :-)
I like the suggestion to move the ctags into a separate process like LSP, but that won't happen "soon".
I like the _suggestion_ too, I like less that it would probably be me who'd have to implement it ;-). But maybe I get bored one day with nothing better to do.
