At least, we now that it is too much.

What about moving the test as is in the TODO section with a comment, next
to the other one, for now?

I hesitated to suggest that before for the above risks, but I was very
naively optimistic that it may pass because the test is not that too
demanding.

Someone suggested to have a "real-time" configure switch to enable/disable
time-sensitive tests.
