Who is using Hot Reload?

I am, and it's awesome!
Thanks for the video by the way!
Quick question though:
Why doesn't it work when the while loop is in the `OutputPid()` function instead of in "Main()"? Does it have something to do with not being able to rewrite the static entrypoint? I don't understand how having the while loop in the `OutputPid()` function rewrites that entrypoint?
Thanks!
