Re: Allocators and tasking.

The programmer need only worry about declared variables which are shared
between tasks.  An access collection is not considered an explicitly
declared variable in this sense.

The implementation must worry about all "hidden" shared data.

Therefore, an implementation must protect its run-time data structures
from simultaneous access.
