Following this idea, I just added to bleadperl (change 21515)
a "make test.taintwarn" target that runs the test suite with the
-t (taint warnings) command-line flags.
It spits out a lot of "Insecure dependency" warnings, and several
tests fail. Notably, tests that install $SIG{__WARN__} handlers
are unhappy to catch taint warnings in it. However some failures
may require more careful investigation.
