+Fix a race in pause / resume handling in wait_computation
+
+The invariant running ^ waiting was not respected, and so the code was
+possibly wrong. If the method is paused while waiting state (but still
+in running before) and then resumed in the same state, the resume part
+will call compute, which will call async_wait when it has finished. Two
+async_wait on the same time lead to an ECANCELED on the first one, and
+so the whole method is aborted.
