As Kunar and Horowitz report, those who were making the equivalent of a hands-free call had an average reaction time 212 milliseconds slower than those who were not.

Validate_ptrs If a pointer that was previously not allocated by malloc is passed to the free call, an error message is thrown and the program is aborted.

If the server receives more than the maximum number, it simply queues the additional RPCs until a free call executor thread is available to execute the RPC.
