Then you can rename y= our debugger to be UltraMI to keep your debugger agnostic the the backend d= ebugger. :-) I noticed in the youtube video that it took 40 seconds to set a breakpoint = at lldb's main function and to run to the breakpoint and hit it. If you try= LLDB MI, I am guessing it will be faster than 40 seconds.
