IIRC, code evaluated by doits is always jitted.
Thus you won't hit a breakpoint in method lookup code which is only 
invoked by non-jitted calls.

In the second case, statement MyClass blah is jitted, and (as long as 
other jitting-conditions have not been met) "TestCase new asdadsadasda" 
is interpreted normally, so the breakpoint is encountered.

Henry
