I would like to find a clean way to suppress the loading of a package
that's defined in initialization cells of notebooks when the package is 
already loaded at the time the notebook is initialized.  The "obvious" 
thing to do is to put code something like this in the initialization:

    x::usage="This should go in the context mystuff`.";
    x = a;
    y = b;

Unfortunately, the symbols x and y both land in the Global`
context instead of mystuff` and mystuff`Private` where they
belong. Evidently, the code inside of If[] uses its own local
version of $Context, rather than the global one that's
manipulated by BeginPackage[] and Begin[].

I know that I could use Needs[] if I put the package definitions
ins a separate file, but that won't do, since I want the
notebooks to work on computers that may not have the package
files installed. Any suggestions?
