It is basically the same as creating savepoint inside trigger (sp)
using WHEN ... DO. I do not know internals much, so I made short test,
and indeed the impact on performace is just too big.

Then I do not see any reasonable solution,
other then making this "optimization" only for operations
not using triggers (no a good idea, I know).
