So for an unknown reason, send_signals() thread was not created or doesn't start.

Example of the output of a success:
----------
test_signals: acquire lock (thread 140735082572960)
test_signals: wait lock (thread 140735082572960)
send_signals: enter (thread 4326952960)
send_signals: raise SIGUSR1
send_signals: raise SIGUSR2
send_signals: release signalled_all
send_signals: exit (thread 4326952960)
test_signals: lock acquired
