Functions don't have supervisors, processes do.

Think about processes as workers in your information factory.

Think about functions as things your workers do -- and ANY worker may perform ANY function (potentially).

With this mental image in mind answer the question:
Which process is calling this function?

The answer will tell you the context of the execution. The context of execution will answer the rest of your questions as a matter of course (and if not, you will automatically solicit many experienced opinions here if you answer the question above publicly in this thread -- and especially if you continue to brainstorm by typing things out here).
