signal: Fix signal-sample.
signal-sample had a nasty nondeterministic bug where the newly created signal might actually be GC'd before it could be returned to the caller. This was able to happen because no reference to the signal was help between creating the signal and returning it. Reported-By: David Hashe <david.hashe@dhashe.com> * sly/signal.scm (signal-sample): Ensure that the garbage collector cannot reclaim the new signal before it is returned.
