That's really very misleading. It is of course possible to write
deterministic
tasking programs, even using only the core language with undefined
dispatching
semantics. If you are using an Annex D compiler with the appropriate
pragmas,
on a monoprocessor, the semantics are designed to be (and are) almost
completely deterministic. The above statement reflects some pretty
significant misunderstanding.
