Presumably this timeout will occur for querying *any* column in the row for that process, not just OperStatus? The code for handling this timeout would remove the row from the list. Or possibly mark it as "dead", and have a separate alarm-driven routine to prune the list of dead entries. I'm slightly concerned about what might happen if there were several varbinds in the same request, all referencing instances from the same (non-responsive) row. If the first varbind processing deleted this entry from the list (and released the memory used by that data structure), this might well confuse the later varbinds. But in principle, yes - you just unlink the entry from the list.
