--------------------------------------

             Summary: Don't retry close() on EINTR.
                 Key: MESOS-3512
                 URL: https://issues.apache.org/jira/browse/MESOS-3512
             Project: Mesos
          Issue Type: Bug
            Reporter: Benjamin Mahler
            Assignee: Benjamin Mahler


On Linux, retrying close on EINTR is dangerous because the fd is already 
released and we may accidentally close a newly opened fd (from another thread), 
see:

It appears that other OSes, like HPUX, require a retry of close on EINTR. The 
Austin Group recently proposed changes to POSIX to require that the EINTR case 
need a retry, but EINPROGRESS be used for when a retry should not occur:

However, Linux does not follow this and so we need to remove our EINTR retries.
