Minor - P4 Running the tests in Travis with progress or Fuubar formatter produced this run: https://travis-ci.org/mongodb/mongo-ruby-driver/builds/388080809?utm_source=github_status&utm_medium=notification
Specifically this one seems legit and likely it should be addressed:
https://travis-ci.org/mongodb/mongo-ruby-driver/jobs/388080829:
1) Mongo::Server::Connection#dispatch when the process is forked disconnects the connection
Failure/Error: if pid != Process.pid
ConcurrencyError:

This one seems weird, possibly a jruby-specific issue: https://travis-ci.org/mongodb/mongo-ruby-driver/jobs/388080825
1) Mongo::Collection::View::MapReduce#each when out is in the options when out is a document iterates over the documents in the result
Failure/Error: Unable to find org/jruby/RubyTime.java to read failed line

This could also be fixable:
https://travis-ci.org/mongodb/mongo-ruby-driver/jobs/388080813
1) Mongo::Server::Monitor#scan! when calling multiple times in succession throttles the scans to minimum 500ms
Failure/Error: expect(Time.now - start).to be >= 0.5
expected: >= 0.5
got: 0.499879
# ./spec/mongo/server/monitor_spec.rb:25:in `block in (root)'
These failures are not happening with the documentation formatter, perhaps because printing each test name out takes enough time to serialize operations.
