        of code collaboration. Positive feedback provides by +1 from committers
        while negative by -1. The -1 also means veto and need to be addressed

   ## Overview
   
   `couch_index` traps exits, but might get an EXIT message from a crashing mrview_compactor, while it only expects message from its own linked compact process.
   
   This adds a new EXIT info handler to `couch_index_compactor` to prevent the compactor from crashing when a compacting process fails, and also cleans up the view compact file.
   
   ## Testing recommendations
   
   We have implemented a new couch_mrview_compact_test `should_remove` which verifies that a crash in the view compacting process doesn't also cause the index or compactor processes to crash. It also ensures `couch_mrview_compactor:remove_compacted/1` is called.
