removal of transactions from clones

This is a patch that fixes part of the problem, but as discussed in the thread,
is not sufficient since the uninstrumented code path will still end up
containing a nested transaction after inlining.

I am attaching this patch for further reference when this PR is picked up
again.  See thread for more details.
