Yeah, you're right.  If there's a "newextra" chunk, that'll get
leaked too.

Even counting that, it's not very plausible that one would SIGHUP a
server often enough that the bloat would become obvious, since these
values typically aren't very large.  But it's clearly a bug.

Patch applied, thanks for the report!
