Subject: 29.2.50; eglot didChangeWatchedFiles runs project-files in an
 arbitary directory, which can be slow
Date: Mon, 19 Aug 2024 12:01:30 -0400
Assuming:
- There is /big-directory which has lots of children, such that
"find /big-directory" takes a long time, e.g. minutes
- .ext is a language whose language server uses workspace/didChangeWatchedFiles

1. emacs -Q

2. C-x C-f /big-directory/file.ext

3. M-x eglot

4. eglot runs (eglot--current-project); suppose project-current returns
nil so eglot--current-project returns:
`(transient . ,(expand-file-name default-directory))

5. The language server starts up and sends workspace/didChangeWatchedFiles to eglot

6. The eglot implementation of workspace/didChangeWatchedFiles runs project--files-in-directory

7. Emacs hangs for a long time as project--files-in-directory runs "find /big-directory"

In particular I've had users experience this when trying to use eglot on
files in large directory trees on NFS, which makes find even slower.

I'm not sure how this could be fixed.

If project-files could run asynchronously (e.g. with make-process),
would Eglot be able to use that here, instead of synchronous
project-files?  Supporting async project-files is on my todo list
anyway.
