After closing KCF tracker , the memory didn't release completely.

I found even if i closed KCF tracking, RAM usage dropped,but didn't release completely(according to the tracker_box, maybe 2% or higher).
Such as, I run the tracker in a child thread, and the main thread just loops（do nothing） after the child thread closed.
What causes this problem?

hi, one question, what kind of tools you've used for monitor RAM? I didn't see any abnormal leakage here.

@rockkingjy I used htop in Linux.
