This PS allows Deckhand to be able to run functional tests with
multiple workers. To achieve that, a document validation bug
was fixed: undeleted data schemas from all previous revisions are
considered. (The test schema-validation-success_add_invalid_document
was failing sporadically because of data race conditions with
only considering data schemas from the last revision with multiple
workers.)
The number of workers for running functional tests via uwsgi
has been increased to the number of CPU cores available on
the server to consistently validate concurrency.
