Has anyone else had difficulty debugging in 2.6?  I used to insert a 
"self halt" at the point I wanted to drop into a debugger, but that 
doesn't seem to work quite right, anymore (has to do with the new 
Exception Handling package?)  I tried "Halt signal", and that seems to 
stop at the right point, but the keys for step (t) and send (e) don't 
work, and sometimes stepping winds up far down the context stack from 
where I was.
