# There are three problems fixed
# a) our build system exports SHELLOPTS which makes testing fail
#    We could have set "unexport SHELLOPTS" in our Makefile, but maybe this
#    will be accepted by community?
# b) Test for a /tmp/xx leftover from running the giant bash
#    test harness. This can happen in the test harness run is
#    interrupted with ^C.
#    Without this test, the test harness will start failing
#    for no real reason.
# c) This script runs all the tests via 'sh <test>'. The problem is that 'sh'
#    might not necesarily be bash. And might produce errors
