page breaks related to header size

[Paul Scott]

2.11.34

In this example there is clearly room for another system on the first 
page.  Removing anything from the header will allow another system to 
move to the first page.  Whatever is removed from the header clearly 
doesn't take as much vertical space as one system.

I have worked for several hours reducing my real example to the 
following.  If a simpler example is needed I will see what I can do.

Thanks,
