This is backwards and extremely misleading; a signal being queued can trigger an immediate context switch (effected via an inter-processor interrupt). See `kick_process()` in the Linux kernel [1].

Signals are userspace interrupts. That's exactly what they are, and they're no more hokey than hardware interrupts (so, pretty hokey).
