I assume the intention was that the "entirely new mechanism" would be
a less risky one.

I may be forgetting something obvious here but is there even a
function to send an interrupt signal? That would trigger the same
behaviour that a user hitting C-c would trigger which would only be
handled at the next CHECK_FOR_INTERRUPTS which seems like it would be
non-controversial and iirc we don't currently have a function to do
this for other connections the user may have if he doesn't have access
to the original terminal and doesn't have raw shell access to run
arbitrary commands.
