Hot Doggies!  Someone used actual profiling data rather
than guessing at nano-optimizations in the code.  Verrrry

GetObjectByName() chases down the list of objects in
G.main->object.  Linear search thru a list, blah, blah, blah.
Sounds like time for a data structure!

Just making up stuff of the top of my head, we could stuff
the names in a dictionary ( aka hash table ) the first time
thru and use that as a name cache.  Like most problems, this
is likely to be more complicated than it appears, but I have no 
doubt we can make this better.

Mega Thanks, Chris for the useful info.  And a fascinating problem.
