Really fix phys_pager:
Backout the previous delta (rev 1.4), it didn't make any difference. If the requested handle is NULL then don't add it to the list of objects, to be found by handle. The problem is that when asking for a NULL handle you are implying you want a new object. Because objects with NULL handles were being added to the list, any further requests for phys backed objects with NULL handles would return a reference to the initial NULL handle object after finding it on the list. Basically one couldn't have more than one phys backed object without a handle in the entire system without this fix. If you did more than one shared memory allocation using the phys pager it would give you your initial allocation again.
