I'm going to echo Mark here.  I assumed that you would not post a patch
which introduced failures in the testsuite.

mi2 is a released protocol; the intent is that we not make
backwards-incompatible changes to mi2-*.exp, at least not without
paying close attention to them.  -i=mi sets mi_version to 3 today. 
Until we're ready to declare mi3 usable, we need to continue caring
about mi2.

You removed the parallel to this failing test from mi-stack.exp; I
assume it should be removed from mi2-stack.exp also?

Mark, could you post a bit of gdb.log?  I don't see these.
