## Message

```
lsp: if language server closes stdout/stderr, break loop (#7229)

Previously we would run these loops indefinitely when a language server
closed its stdout/stderr and the `read_until` returned `0` bytes read.

Easy to reproduce: start Zed with LSP attached, `kill -9` the LSP, see
logs accumulate.

Release Notes:

- Fix high CPU usage when a language server crashes (or closes its
stdout/stderr on purpose).
