It can be done either way. Grinding userspace code as well is more uniform, as there's no need to say "this clone should not be followed, as it will become a UML process". On the other hand, not grinding processes means you don't need to figure out how to get the valgrind engine into your processes. Jeff -- Work email - jdike at linux dot intel dot com
