# Note that there are several places where the value of 
# tcltest::currentFailure is stored/reset in the -setup/-cleanup
# of a test that has a body that runs [test] that will fail.
# This is a workaround of using the same tcltest code that we are
# testing to run the test itself.  Ditto on things like [verbose].
#
# It would be better to have the -body of the tests run the tcltest
# commands in a slave interp so the [test] being tested would not
# interfere with the [test] doing the testing.
