I have never done this but setting "OverSubscribe" in the appropriate
place might be what you are looking for.

Personally, however, I would be a bit wary of doing this.  What if
someone does start a multithreaded process on purpose or by accident?

Wouldn't just using cgroups on your login node achieve what you want?
