It looks like by setting the Resource Manager tid to 0 (via SM_HANDOFF), 
the pvmd will believe that it has no resource manager and go back to 
using the built-in methods.

An alternative which I expected might work would be to simply kill the 
Resource Manager process.  However, from reading the source (3.3.11), it 
looks like the pvmd will not detect that a dead process was the RM, and 
clean-up.
