- Fixed a critical regression caused by :ticket:`3061` where the
NEVER_SET symbol could easily leak into a lazyload query, subsequent
to the flush of a pending object. This would occur typically
for a many-to-one relationship that does not use a simple
"get" strategy. The good news is that the fix improves efficiency
vs. 0.9, because we can now skip the SELECT statement entirely
when we detect NEVER_SET symbols present in the parameters; prior to
:ticket:`3061`, we couldn't discern if the None here were set or not.
fixes #3368
