What 2 reasons? The reason I had the paragraph below is that I was sure I
answered to everything you said, so I have no idea what you mean.

Okay, so, my point you replied to was that I allocated 200M when I needed them, and I am releasing them because I no longer need them. You are opposing that with I "lost the moral authority to say that it's not OK for Emacs to still uses up 200MB".

"moral"…? Seriously? ☺ Was that some code of conduct I violated by allocating 200M, or what does mean "I lost moral authority"? Is that a technical reason you referred to? ☺
