What David meant was that "root will always have a slot" doesn't *actually* help unless you *also* have a way to actually *spawn* such a process. In order to do the ps, kill, and so on that you need to recover, you need to already have either a root shell available, or a way to *get* a root shell that doesn't rely on a non-root process (so /bin/su doesn't help here).
That's right, although it's worse than that. You need to have a process with CAP_SYS_ADMIN. If root processes normally have that capability then the reserved slots may well disappear before you notice a problem. If root processes normally don't have it, then you need to guarantee that one is already running.
