a per-process limit should be enforced as well, to prevent a more 
limited-scope DoS.. and perhaps if we get fancy, reserve a slot in the 
per-process quota for a process running as root to send to, to prevent 
processes from rendering themselves more unkillable by keeping their own 
signal queues full , thereby rejecting KILLs, XCPUs, STOPs, and the like?
