monitor command.

Can you point out the bug number? I really don't expect that we keep
integrity of the disk after several resets, at least I wouldn't if it
was a bare metal machine... Anyway, I've made some changes to the
code, mostly removing unnecessary imports and having some messages
explaining what the test is doing... I am just not convinced that this
test should pass in all circumstances (I tried here and it does pass,
by the way).
