perf: allow profiling of more than one run
By default, we still profile the first run only. However profiling more run help
to understand side effect from one run to the other. So we add an option to be
able to do so.

$ hg add foo
mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:
$ hg ci -m foo
error: pretxncommit.nocommits hook failed: no commits allowed
transaction abort!
