------- Additional Comments from Christophe Dumez <christophe.dumez at intel.com>
New proposal based on Jocelyn's feedback.

I'm now checking the pending map explicitly which allows for some optimizations
in the case where we have both a pending creation AND a pending removal (in
which case we can simply cancel the pending operation and return early).
