Well this memory profile is something that I would expect to be low and
irrelevant. I don't have a proof, so marked as a suspicion.
I wouldn't be surprised if that'd be something that touched MacOS users only -
I've seen plenty of complains about the performance and experienced it too, but
AFAIK we're smaller crowd. Suspicion coms from the fact that I cannot see where
the data is going and leaks tool is reporting low usage, so most likely this is
outside of C realm.
I've done some extra testing, since I wouldn't be surprised if some release on
a string was missing or something. On a fresh instance blinking cursor is
enough to raise memory usage. 10mb over 4.5mb and garbage- didn't releaes
memory.
I think I can reproduce test case and even think what might be the cause, as I
looked around MacOS code for couple of minutes.
Best,
