Through chaining of interrupts, it is easy to flood the server with

interrupts. For instance, in trap city, interrupts piled up on an info

system, since each interrupt launched a new one. This should be

mitigated by adding a kind of interrupt that makes sure it is the only

interrupt of its kind.

Also, this is a security risk that is trivially exploitable: just have a

luaatc component launch two interrupts on itself, which should quickly

grind the server to a halt.
