Threads or other forms of multi-tasking are not addressed in the
C++ draft standard, and are not likely to be.

No.

You should expect exceptions to work correctly in a C++ implementation.

But if an implementation provided a multi-tasking capability and
documented that, for example, you had to disable exceptions in order
to use it, I don't believe that would violate any provision
of the standard.
