IMHO this does not make much sense.

For the user-programmer, the relevant difference between tasks and 
threads is that thread share memory.

This results in the increasing complexity with mutually accessed 
variables which of course provides a real challenge.

But you can think of a programming paradigm (=CILK") that does not allow 
the user programmer to share the variables between the "tasks" even 
though the "tasks" in fact are threads as far as the OS is concerned.

Not the tasks switch is done with a lot less overhead as the OS does not 
need to change the environment (such as MMU tables), the cache is used 
more efficiently (especially on ARM as here the cache needs to be 
cleared with each change in the MMU tables).

The communication between the tasks (here done not by the user but by 
would be automated the system (e.g. CILK) would be a lot faster when it 
uses threads instead of processes, as it could easily make uses of 
shared memory (though hidden from the user).

Moreover, while debugging multiple threads is more difficult than 
debugging single threaded applications, parallel debugging of multiple 
applications is still more heavy.
