Are you sure that ltp-pan actually passes the test return value? As far
as I can tell it actually increments the exit_stat variable on error
then does exit(exit_stat).

So I would say that the only guarantee that you have is that non-zero
return value from ltp-pan means "everything went ok" and non-zero
"something went wrong".

Frankly at this point I would rather kept the old test execution scripts
as they are and put more effort into the new execution framework.
Hopefully I will have a bit time to invest into it once we are done with
the release.
