No, because the OS isn't reclaiming the memory specifically; and this only works with overcommit and/or swap. The memory isn't actually being reclaimed, it's being paged out. If your application actually begins to use the memory but never uses the data again (eg; can't reference it) it will continue to eat memory until the OOM killer kicks in or the system crashes.
Well, unless your program is particularly long lived, it will be reclaimed. There are many tools that could reasonably forego `free` for their entire runtimes.
I presume we're talking about long running programs otherwise the conversation isn't really super useful since for any program, short or long memory is reclaimed when a program exits (well, at least on any modern OS).
