Message:

kmk,kWorker: Assign processor groups to kWorker processes. Added --special-env hack for having a mspdbsrv.exe instance per processor group (using _MSPDBSRV_ENDPOINT_). This was complicated by PCH requiring to share .pdb file and therefore mspdbsrv.exe instance, requiring a mspdb100.dll re-init hack to disconnect kWorker from the previous mspdbsrv when switching. fun.
