I don't see a way to it cleanly in DllMain. You could ignore
thread shutdown and let the system clean it up at process exit,
but then you'd leak threads when an app keeps loading and unloading
However, it might work if you start the dummy thread right before
running the first custom action and take it down after the last
one has finished, e.g. in ACTION_FinishCustomActions.

Running the custom action in a separate process.

Sorry, I should have looked it up:
The interesting bit is in the comments.
