Two independent instances of the ControlSerializer class are in use at the IPC boundaries, one in the Proxy class that serializes data from the pipeline handler to the IPA, and one in the ProxyWorker which serializes data in the opposite direction. Each instance operates autonomously, without any centralized point of control, and each one assigns a numerical handle to each ControlInfoMap it serializes. This creates a risk of potential collision on the handle values, as both instances will use the same numerical space and are not aware of what handles has been already used by the instance "on the other side". To fix that, partition the handles numerical space by initializing the control serializer with a seed according to the role of the component that creates the serializer and increment the handle number by 2, to avoid any collision risk. While this is temporary and rather hacky solution, it solves an issue with isolated IPA modules without too much complexity added.
