Signal connections persist until they are explicitly disconnected, the
signal is destroyed, or the slot is invalidated somehow (e.g. it's
associated with a trackable which is destroyed).

Note, however, that the libsigc++ signals are an entirely different
concept from POSIX signals described in signal(7) and signal(2).
Attempting to relate them is not useful.
