- * An active query, always associated with a CLCachedEntry.

- * In the case of a CLCachedEntry created by an explicit {Cert,CRL}Cache op,
- * there can be multiple queries active for a given cached cert. In
- * the *GetFirst*FieldValue case, there is a one-to-one relationship between
- * the CLQUery and its associated cached object.
- *
- * Out of paranoia in the {Cert,CRL}Cache case, we store the handle of 
- * the associated cached object, not a ref to the object, in case the
- * cached object has been deleted via *AbortCache. We could ref count,
- * but that would require a lock in CLCachedEntry...looking up an object
- * in the session's cache map should not be too expensive.
