Yeah, but the isolation sometimes got broken as code getting added like
this.  So we need a automatic way of detecting breakage.

I thought about adding a perf test entry running python/twatch.py, but
it will not work for an installed perf binary since it cannot find the
twatch.py script and perf.so extension files which are not installed.

Now I'm thinking of making it build-time test so that it can be executed
by make when specific argument is given - e.g. make C=1 ?

Thanks
