We don't know much about black holes but we *do* know a good bit about
fluid dynamics and field mechanics. Using just a few principles from both
these disiplines indicate that holes don't just 'merge'. The gravity
fields set up by colliding black holes would cancel each other along
the intersection axis in the time interval prior to collision. This  
interval is longer than you'd expect as two black holes would most   
likely collide at oblique angles and go into a tight spiral orbit about
each other before collision.

Imagine what this means! Two little mass bottles under incredible 
pressure suddenly having their corks pulled out. Calculations are a 
little intense but the result can be summed up in a word...
 

                      BBBBB      OOOO    OOOO    MM    MM   !!
                      B    B    O    O  O    O   M M  M M   !!
                      BBBBB     O    O  O    O   M  MM  M   !!
                      B    B    O    O  O    O   M      M

Just a bit over 27% of the total mass of both holes would be converted
into PURE ENERGY! Another 18% is released as actual mass and the remaining
forms into a black hole with severe spin and g-field fluctuation.

We're talking here about a bang that would make a supernova seem like a fart
in an elevator. :-)

The values above were calculated on a Cray by a group of English Profs. 
at Oxford (I believe) and may not be accurate as they were pulled from the
dregs of my memory. If anybody's interested I can dig up exactly who and
where this info came from and provide either referances or more info.

Sorry I don't know if spin or charge would make a difference but I
suspect they would be negligable considering the overwhelming g-force 
involved.
