Sorry, but you seem to have missed the second part of the explanation of
what free() does. Just because it doesn't free the memory for use by the
system at large (i.e. Winblows) doesn't mean free() would do nothing at
all. It *does* make the memory available for use by later malloc() calls
in the same program.

No. This is not what _heapmin() is for, originally.
