Filipe Manana commented on COUCHDB-913:
---------------------------------------

Adam,

Thanks for the review.

I updated the term_cache_trees module:  http://github.com/fdmanana/couchdb/commit/e53d37f65f5984bdcf239315a6394f1e8dbd2adb

(it is based on an ets implementation, so it might have still more room for optimizations)

As for the leak after view compaction, I think just the following line solves it:  http://github.com/fdmanana/couchdb/commit/4c92720a5b1fb6607a09bef592345fd5d80d40fa
