Which areas this variable has influence on? Help info doesn't tell much. It's off by default, but COPs and DOPs are multithreaded anyway. I'm particularly interested with SOPs, has anything changed recently with regards to multithreading support in Houdini?

AFAIK this is an experimental feature which doesn't bring you yet any advantage except sporadic crashes . I think it will allow in a future to cook sops inside many objects simultaneously.

This environment variable enables the threading of objects. As stated it is not supported at this time.
