If you want process A to do the killing, and process B to do the reaping, then you need a new syscall regardless.

(Why have two? To improve throughput. A can spend all its CPU cycles on identifying useful things to kill, and B can spend its CPU cycles on actual reaping. You can then adjust the relative priorities of those two tasks independently of each other with the usual process-management techniques.)

Interesting point! Technically process B (or thread B) could do the kill as well after A picked out a target, but it does make sense to have a high-priority process do the kill and a lower-priority (but still higher-priority-than-normal) process do the reclamation.
