Let us calm down, and avoid pushing changes which are worse than the
issue they try and correct. I will not publish anything on these issues
before this week-end. Instead of modifying the mutex-torture unt test, I
will try and write a condvar-torture unit test, which exhaustively test
all the return values of pthread_cond_wait/rt_cond_wait, including
interruption by signals during the cond_wait, and the epilogue.
