File watching doesn't work between shared folders (parallels)

[joaomoreno]

Testing #29478

I'm not getting file events for a Parallels shared folder from macOS to Linux 32 bits, independently of multi root. It doesn't seem to be a regression, since it fails on both the old and new file watchers.

@joaomoreno to be clear the events fail within Linux when changing files on mac or vice versa or actually both directions?

This may just be a limitation of the underlying native watcher infrastructure, not sure we can do anything about it.

macOS is the host OS. Linux guest is the guest OS. Code is running inside the Linux guest OS.

I can reproduce with our old watcher for both macOS => Windows as well as Windows => macOS. I do not think this is critical and I do not think we can actually do something about it other than falling back to polling when we detect this (which I am not sure how to...).
