Leak means in that case, that the WM_TIMER refresh of each app consumes a lot
of additional memory which may result in BSOD due to lack of memory. It's not
enough to free it after the end of application, because it leads to an
unexpected early end...

AFAIR as principle of a cache it will reuse the freed DC at next
CreateCompatibleDC-call, but the next identical call will consume the next 4 k.
Just to make clear it can't keep unchanged...
