should.py doesn't timeout with launcher
On current version of Vidjil just launch:
python3 should.py --launcher 'valgrind --tool=memcheck --leak-check=full --show-reachable=yes --trace-children=yes' should-get-tests/stanford-germlines.should-get
Valgrind produces lots of output (see #19 (closed)) and should.py
hangs.
