D8189: testlib: add a small scrip to help process to synchronise using file

[marmoute (Pierre-Yves David)]

marmoute added a comment.


  By using explicit wait on signal (through the fs) that each process reached the appropriate file. We avoid flackyness. There are already multiple use of this approach in the test suite, that does not suffer from flackyness (unlike the wheelbarrow of flaky test relying on sleep for sync).
