 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 :-)
