> Key: MESOS-5882

> Project: Mesos
> Issue Type: Bug
> Components: stout
> Reporter: Alex Clemmer
> Labels: mesosphere, stout
>
> `os::cloexec` does not work on Windows. It will never work at the OS level.
> Because of this, there are likely many important and hard-to-detect bugs
> hanging around the agent.
> This is extremely important to fix. Some possible solutions to investigate
> (some of which are _extremely_ risky):
> * Abstract out file descriptors into a class, implement cloexec in that class
> on Windows (since we can't rely on the OS to do it).
> * Refactor all the code that relies on `os::cloexec` to not rely on it.
> Of the two, the first seems less risky in the short term, because the cloexec
> code only affects Windows. Depending on the semantics of the implementation
> of the `FileDescriptor` class, it is possible that this is riskier to Windows
> in the longer term, as the semantics of `cloexec` may have subtle difference
> between Linux and Windows.
