I'm still doing testing on System::update() with the large systems that are 
giving us problems.  I haven't been able to isolate the problem yet.... but I'm 
working on it.  I am thinking that the issue might actually be elsewhere but 
it's causing the failure in System::update().... I'm somewhat hopeful that 
after I track it down we might be able to revert System::update() to the 
previous algorithm.

Sorry it's taking so long.... just hard to debug these big problems.
