VSCode: Something odd with language-server local rpc communication: too many new TCP connections for POST /exa.language_server_pb.LanguageServerService/ProgressBars

[nom3ad]

While trying to debug OOM caused by Codeium language-server process, I came to notice that something is strange with the localhost bound communication between processes. Even though this might have nothing to do with OOM issue, I think this could be a bug that causes some performance damage.

• ~1000 HTTP calls being made for POST /exa.language_server_pb.LanguageServerService/ProgressBars per minute. (Even when there is no activity in the editor)
• This behavior is not found for Vim implementation
• No connection reuse for these calls - New TCP connection being made for each HTTP/1.1 requests. This is the case for both VSCode and Vim.

Nitpick:

• If it's possible to implement parent-child process communication over stdio instead of TCP, that would be even better.
