If you have a client-server architecture, it would be really nice to be able to debug both the client and the server in the same lldb process, because then you can add tooling on top of lldb to do things like "step in across remote protocol dispatch". And in client-server systems it is often the case that the client and the server run on different OS-es. Jim

Sorry if I sounded mean before, that wasn't my intention at all. I assumed you meant just using lldb-server, but with this explanation it makes sense why you'd debug both and now I can see why you run into this. 

What do you think about caching at most two instances per kind (summary/snythetic/formatter) per entry? The two isn't from "client&server" but from having at most two different ones (gnu&msvc).
