Re: back-meta: possible bug in the handling of the candidate targets (ITS#2935)


the only case when multiple candidates are legal is when
doing a search.  Without re-reading too much the code
(which, I admit, is a bit obscure), targets that were
candidates for earlier operations in the same connection
are preserved in the hope they can return something useful,
without strictly checking if they're still candidates.

If they don't, theyre adding a minimal overhead, because
they're returning nothing and, in the meanwhile, other
targets are served.  It is likely thaat at some point,
while reviewing the code, this gets fixed (if it is an
error; if there's a good reason for it, better leave it
in place).
