run-tests: allow some slack about 'waiting on lock' message It is common to run the tests on very loaded machine when concurrent run might take a bit longer. Such message are usually harmless, but anoying as they break the tests. Test that explicitly depends on this value have been adjusted. This make them more robust anyway. A fun case was `test-clone-pull-corruption.t` which, without the previous changeset introducing extra flushing, ended use having a line 31 (`pulling from ../source`) changing order because the warning message was no longer flushing stdin before using stderr (stderr being invisible in the test).
