Ok, I'm trying to write a simple testcase for the newly created Display 
class and I'm uncovering some of the rust that's built up over that last 
few months :P. Essentially the test I want to create consists of having 
a program:

  int x;
  x = 1; *
  x = 2; **

Then creating breakpoints at the two lines marked by * and ** and then 
printing out the variable values (via Display) at those two points. 
Right now I'm using AttachedDaemonProcess to create a proc that's 
attached and blocked at the first address of the program. However I'm 
having some difficulties find the right sequence of calls to add the 
breakpoints. Currently I'm trying LineBreakoint.addLineBreakpoint() and 
then adding my own delegate observer to pick up on the calls. Is this 
correct, or is there something else I should be doing?

I've attached the test case as it currently stands. It currently times 
out at the assertRunUntilStop("adding bp") on line 91. I also noticed 
that the addedTo/deletedFrom/addFailed messages are not being forwarded 
to the observer delegate. I added this to my local build but it didnt' 
change anything.
