Sigh!  Finally.  If anyone is interested:

I tried the "advice" but for some reason, the advice didn't trigger when Tramp is loaded.  I assume that is because it is getting autoloaded which doesn't use load?  The ^G didn't give much of a clue.  The stack I got was:

But why was tramp loaded in the first place?  So, I ended up removing the rlogin.elc and the tramp.elc and added

(debug-on-entry 'tramp-register-file-name-handlers)

just after it was defined.  I didn't that a couple of different ways and got the same stack (below).  The stack seems like it left off the initial N frames.

But I finally figured out that it was because rlogin-directory-tracking-mode was set.  I found that set in one of my older init files.  So, I cleared that.  That solved the initial problem of starting emacs and immediately doing the rlogin.  But I also have ido set and I was sure that it called tramp too.  So, I triggered ido to load tramp and found that there is ido-enable-tramp-completion.  I think I'm not tramp-less :-)

Thanks guys.
