the tearDown target should take care of that, unless anything kills Ant,
that is.

True.  I guess we never envisoined that.

Several JUnit tests use java.io.tempdir (need to grep through it), most
if not all AntUnit tests import a common file that defines the setUp and
tearDown targets and properties input and output which the tests use.
If you change that file (src/tests/antunit/antunit-base.xml) it should
take effect for a whole bunch of AntUnit tests immediately.

That would work for our JUnit tests, for AntUnit we'd have the build
file name (the one importing the base file) but not the executing
target.
