:vim[grep] throws many errors and is extremely slow when searching in symlinked directories

[jamilraichouni]

Hi!

First I want to say thank you for this really helpful plugin (especially when combined with vim-fugitive).

When I search something recursively in Neovim 0.9.2 via the command

:vim /PATTERN/ /path/to/a/symlinked/dir/**/*

I get many E937: Attempt to delete a buffer that is in use: /some/path error messages.

When I uninstall vim-symlink the same command runs just fine and very quick.

BTW:
Installing the optional dependency moll/vim-bbye does also help. At the same time I'd be happy to avoid installing an additional plugin.

I created a Dockerfile with which one can easily reproduce the error.
To build the Docker image place a file named Dockerfile in some temp directory and run

docker build -t bug .

in that directory.

To run the Docker container run docker run --rm -it bug afterwards.

When the optional dependency moll/vim-bbye is being added (4th RUN statement below) the search runs without any error:
