The point is that a pattern match that happens asynchronously might not
leave behind $MATCH / $match etc. values owing to other pattern matches
going on, period, whether synchronous or async.  Two signal handlers in
the example was just to set up a way to get into the situation; a glob
that takes several seconds to complete might just as easily do it, but
is hard to invent for purposes of example code.

I'm the tiniest bit worried that there's a way $MATCH et al. might be
left pointing at garbage memory, but I don't really think so.

} I don't think that's an issue.

I don't think it's an issue either, but it's going to do the potentially
unexpected thing more consistently now, so I wondered if it should be
documented.
