  Log Message:
  -----------
  Don't hold the Target's ModuleListLock over running LoadScriptingResourceInTarget (#138216)

That calls an unknown amount of Python code, and can do quite a bit of
work - especially if people do things like launch scripted processes in
this script affordance. Doing that while holding a major lock like the
ModuleList lock is asking for trouble.

I tried to make a test that would actually stall without this, but I
couldn't come up with anything that reliably failed. You always have to
get pretty unlucky.
