I was (of course) presuming that "tasklets" would get those capabilities if 
they were to replace tasks. That's what I meant about "suspension", which is 
not currently allowed for threads in Ada (parallel code is not allowed to 
call potentially blocking operations). If that was changed, then all forms 
of existing task communication would be allowed.

I'm less certain about the value of priorities, most of the time, they don't 
help writing correct Ada code. (You still need all of the protections 
against race conditions and the like.) I do realize that they are a natural 
way to express constraints on a program. So I admit I don't know in this 
area, in particular if there are things that priorities are truly required 
for.
