- Is the "why not" sarcastic, as in you're agreeing it's a waste?

verify that the process isn't taking too much RAM?
I would say the 'why not' isn't being sarcastic but pragmatic. (And I would expect Linux to work similarly). After all if you have a system with X amount of memory, and total memory demand for the other processes is 10% of X, what is the issue with letting one process use 80% of X with memory usages that is easy to clear out if something else wants it. A read only page that is already backed on the disk is trivial to make available for another usage.
Memory just sitting idle is the real waste.
