	Hrm.  

	Okay, let's say there are two objects that are 
freefalling from the event horizon to the singularity in a 
black hole.  The maximum proper time from event 
horizon to singularity is, say, 50 usec.  Object A is 1 
usec ahead of object B.  After object A has traveled for 
25 usec proper time, it emits a photon.  Object B absorbs 
this photon at some point after object B has traveled for 
at least 25 usec, so the energy represented by this 
photon, even though it reaches the singularity after the 
rest of object A, nevertheless reaches the singularity 
after no more than 50 usec of proper time.

	Okay, that makes sense.  Thanks.
