And I'm not sure this comment is that useful. I mean, the geometryWorker.onmessage code which calls this function is only a few lines up, which should make it obvious that the message is coming from the worker, not the  connection. Of course, if you want to rename the function to make it more obvious, go ahead, but I'm against the comment because it describes something about the operation of the program that seems to be well described by the code itself, and which could (at least theoretically) change.
