- Actually, it can be simpler yet, as Waterloo's Thoth system showed.
- Subject to some sort of suitable protections (perhaps including a way
- to ignore signals), when a thread receives a signal, it drops dead.
- No signal handlers or blocking. If you want some sort of recovery
- action, have another thread waiting for the first one to die: it has
- access to all the first thread's data, so it can do whatever recovery
- is appropriate.
