Wow!

p/s fluid is like hydraulic fluid (if not exactly the same), its not supposed to boil when kept in a purged (no air) system. And since it doesn't run through the engine block like coolant and oil, I don't think there should be too much heat transfer.

My guess is that somehow air is getting into the system. In any event, it definitely needs to be checked out by a tech.
