Title: [Process] Fixed a problem on RHEL5 where the exit code was incorrect

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
License of the code: MIT

RHEL5 will intermittently result in an exit code of -1 due to `proc_get_status()` being called after the process has completed but outside of `updateStatus()` which saves the exit code.
