// NOTE SIZE: Step 2 will break this into 2 classes, a shared object class that
// just has cAlt and h, and derived off that will be exclusive/share
// class that also has the tid.  cShareLock and cExclusiveLock will
// both be in the same place, we just have to fix DCOBJ first.
// That way we can go rederive the classes that hang off the
// object that only use exclusive locking to save 2 more DWORDs!
