Running a bunch of tests with `yes` is broken

[Serpentian]

Commit 3b0ccd0 breaks running tests with:

./test-run.py --builddir=.. $(yes 7253 | head -100)

After this commit only one test is launched, which is unacceptable, as It's the only way to check, whether the test is flaky

Confirmed. Sorry for the inconvenience.

A temporary workaround is the following (needs patching test-run).
