Thanks.

Agreed.

You can run the testsuite in parallel make mode nowadays.   E.g.,
on my laptop, "make check -j4" only takes around 5 minutes.
You can also run only the MI tests with:

 make check RUNTESTFLAGS="--directory=gdb.mi"

although, I don't think there's any test covering these MI
commands.  :-/

Looks obviously correct to me.
