Subject [jira] [Created] (MESOS-1432) Atomically set close-on-exec where possible.

Benjamin Mahler created MESOS-1432:
--------------------------------------

             Summary: Atomically set close-on-exec where possible.
                 Key: MESOS-1432
                 URL: https://issues.apache.org/jira/browse/MESOS-1432
             Project: Mesos
          Issue Type: Bug
            Reporter: Benjamin Mahler


In our multi-threaded code, there is a race between opening a file descriptor and setting
close-on-exec on it: if a fork occurs between these operations then we have leaked the file
descriptor to the child process.

Some required reading:

We should do an audit of all of our code to ensure we're doing avoiding this race where possible.
