[1.4.0.0b1] Local Dispatcher not updating CPU/Memory usage

[vNicolini]

Version: Gaffer 1.4.0.0b1-windows
Third-party tools: Arnold
Third-party modules: None

Description

While testing Gaffer 1.4.0.0b1 new local dispatcher i've noticed that the CPU and Memory usage aren't updating whatsoever (they stays at 0.00 for the CPU and 0.01GB for the Memory throughout the whole renderjob.

From what we discussed with John over on the Discord it seems to be a Windows only behavior.

Steps to reproduce

1. Create a local dispatcher
2. Dispatch a job locally
3. Observer CPU and Memory usage values

just to keep track on it, the behavior remains the same on beta6 on both Arnold and 3Delight renders
