--------------------------------------------------------------
This approach appears to be a dead end. In particular PkQuery can not be
combined with entities with "generated" PK, as "generated" PK bypasses Cayenne
PkGenerator. Still attaching a working PkQuery patch with a single simple test.
Maybe somebody finds it useful.

> Will create a new query - PkQuery, that will be used to reserve a PK for a

> Not sure if there is a point in batching it (fetch multiple PKs in one shot?)
> Won't do batching initially.
