 Any sleeping behaviour that you need to perform inside a `SIGNAL_HANDLER` proc must be called asynchronously (e.g. with `INVOKE_ASYNC()`) or be redone to work asynchronously. 
 
+#### `override`
+
+Each atom can only register a signal on the same object once, or else you will get a runtime. Overriding signals is usually a bug, but if you are confident that it is not, you can silence this runtime with `override = TRUE`.

+```dm
+RegisterSignal(fork, COMSIG_FORK_STAB, .proc/on_fork_stab, override = TRUE)
+```
+
+If you decide to do this, you should make it clear with a comment explaining why it is necessary. This helps us to understand that the signal override is not a bug, and may help us to remove it in the future if the assumptions change.
