Regularly causes logins, ssh, sudo, df, and other commands to hang (for all users)

[puterboy]

I run google-drive-ocamlfuse as a non-privileged user (on Ubuntu 18.04)
It has worked well for years.

Starting a few weeks ago, it started to cause various services on my system to hang (forever), including login, su, sudo, df.
Other processes and commands continue to work.

The problem resolved immediately upon killing the google-drive-ocamlfuse process.

If I didn't already have a login shell to kill the process, I found myself completely locked out -- I couldn't even login from the console, not even as root or any other user. This left me no choice but to ctrl-alt-del

At first the problem seemed to occur only several or even many hours after launching google-drive-ocamlfuse so I thought perhaps it was triggered by some process accessing my google drive.

But today it locked things up each time immediately after launching google-drive-ocamlfuse -- without ever even accessing the Google drive.

Debug, even verbose, doesn't show anything.

THIS IS A CRITICAL -- EVEN FATAL BUG.

Any idea what could be causing this????

Note: I am running v0.7.27 which seems to be the most recent version in your PPA for Ubuntu 18.04.
If you provide later versions, I would be happy to test if the bug applies to them too.

Your best option is to compile the application on your host with opam, if you can, to get the latest version. Note that now Google requires a personal client id to make it work.
