Stack (C time) space allocated for use by the threads can be returned to the OS, as a separate virtual allocation is made for each thread when it is created, and return to the system when the thread is destroyed.

Heap space used by the threads comes from the same, single, virtual allocation made by the process at startup, so any expansion of the heap for use by the threads cannot be returned to the OS. However, it is available for re-use by the main thread or any subsequent threads that may be created. Technically, this is not a leak.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
