"This requires all processes to participate in a time consuming
global computation."
The addition is:
"... consuming global computation, or to periodically poll for
potential messages or data requests to receive and act upon."
The sentence following it would change to:
"The use of put or get calls avoids the need for the global
computation or the explicit polling."
