Problem

Listing the contents of a directory in a shared volume with 200K files from within a ubuntu container hosted in windows gets stuck.

How to reproduce

1. Install Docker Desktop 2.2.0.3 (42716) stable on Windows 10
2. Configure docker to work in WSL (Ubuntu 16 distribution)
   • Expose daemon on tcp://localhost:2375 without TLS
   • In WSL, define environment variable DOCKER_HOST=localhost:2375
   • In WSL, in /etc/wsl.conf in the [automount] section, define root = /
3. Create a folder on the Windows host that contains 200,000 files (even small ones). e.g. c:/temp
4. Run a docker container, mapping c:/temp on the host to /opt in the container as follows: docker run -it -v /c/temp:/opt ubuntu bash
5. In the bash prompt of the container run cd /opt and then ls

Expected Result

The ls command will start to list all files in the c:/temp folder.
This can be expected to take some time, but it will begin almost immediately.

Actual Result

Nothing is printed and the shell does not respond.
Moreover, CTR C does not interrupt the ls command.
The only way I found to stop the container is to restart Docker Desktop
