   There is actually no race on current_mode, because the mode can not change unexpectedly, until _starpu_notify_data_dependencies() is called further down. Valgrind can not know about such software rwlock.

   TODO1: This is temporary. It perhaps does not pose problem because only the worker takes this mutex. Fixing this will require changing the scheduler interface, so that the schedulers themselves take the scheduling lock, not the caller. Filter it out for now, so we can see other races more easily.
