If you're using a signal from two threads concurrently, you will most
likely see random crashes and other bad behavior. Signals keep a lot of
state, even when they are being invoked, so just about anything can
trip it up.

Ideally, a thread-safe Signals would allow you to invoke in several
threads at one, disconnect signals in several threads concurrently,
