Thanks, Stas. You're right about the problems with $HOME,
and I'll take a more careful look at it, as well as your
other comments. In the meantime, here's something that
inserts the data at a later stage, and yet still can get
overridden by explicit arguments to t/TEST. In this
attempt, all the changes are made to Apache::TestRun.pm.
