Review request for mesos and Joseph Wu.


Changes
-------

Rebase.


Repository: mesos


Description
-------

`Owned` pointers are copied in multiple places of the default executor.
This violates the semantic of owned pointers and works only because
`Owned` is currently implemented with `shared_ptr`, it would otherwise
lead to double-freeing the pointers.

This patch changes those places to use references to the original
`Owned` objects or raw pointers instead of copies.


Diffs (updated)

Thanks,
