Thanks for the patch.

However, I believe that this is no longer a problem in 5.12, even though the
test's code is unchanged, because those tests are now run with dist/IO/t as
the current directory, only IO's tests run in that directory, and IO's tests
are run sequentially.

Hence I believe that the interaction with other tests is gone now. Certainly,
I've not had problems since the grand rearrangement of the code.
