Work Description: rmannibucau commented on issue #4965: BEAM-3119 ensure
the metrics thread pool is related to an execution
URL: https://github.com/apache/beam/pull/4965#issuecomment-386053451
Will not help but the timeout should be infinite for this one since it must
stop before exiting. Also the build env should probably guarantee the machine
is not overloaded, 10s for that test is likely more than 9s of a blocked
machine cause of a lack of resource.
