This is the exact sequence, I reproduced it with 4.99.16/amd64 as well:

mkdir -p foo/blah/baz
mkdir -p blah/baz
mkdir baz

mount -t union foo/blah blah
mount -t null blah baz
mount -t null blah/bar baz/bar

First time that you run the last command it's possible to cancel
the process, but in the next run it will hang... even you couldn't
do 'ls' anymore :-)
