No problem in code. Others could speak to the compatibility
with their applications.

But I'd probably reference count at the request (aka statement)
level for the following reasons:

1) It would be more consistent with the way we reference
count the existence locks for base relations and indices;

2) Long-running connections might defeat the strategy;
