[COMMITTED PATCH] fix _dl_close_worker warning

[Roland McGrath]

I also added a comment while I was there, which it seems to me should have
been there to begin with.

Gary, when we vet changes by eye we are assuming that the submitter has
tested them and this includes verifying that they do not introduce new
compiler warnings (except the occasional 'might be used uninitialized' when
it's unavoidable without adding dead stores).  Please make sure you do not
introduce any warnings in any future changes.


Thanks,
Roland
