All those now supervised by the trap. To reproduce, e.g., for 
meta/recipes-devtools/buildchroot/buildchroot.bb, put a 
  false
after, e.g., the trap line simulating the following multistrap call to
have failed. Then, without this patch,  ${BUILDCHROOT_DIR}/proc is still
mounted. With this patch, it's unmounted.
Same procedure applies to the other cases.


Kind regards,
