Thread synchronization/safety when multiple commands run simultaneously?

[csteele]

For some reason I'm not seeing reference to this topic.. where the same sort of issue was discussed, and responded to by Hubitat.

What is Hubitat's thread safety model?

I have some questions about thread safety. Will Hubitat execute all of script's methods on a single thread, or multiple threads? Methods such as installed(), updated(), various event handlers.
