For really flaky situations, you can use a loop, instead of the unless statement, to rerun failing specs multiple times.
tries = 0
while not $?.success? and tries < 3
puts "[#{Time.now}] Failed, retrying #{File.read(rspec_failures).split(/\n+/).count} failure(s) in spec:suite:#{suite[:id]} ..."
Rake::Task["spec:suite:#{suite[:id]}:retry"].execute
tries += 1
end
