[TIP] After upgrade to coverage 3.0.1, nosetests --with-coverage shows zero lines covered!

[Ned Batchelder]

OK, I'm able to reproduce the problem with these instructions.  I'll dig 
into what's going on here.  First suspect is some very tricky code to 
make decorators work on 2.3, which uses the settrace function to poke 
values into frames.
