Now it's clear. So this looks like one of the options considered by
David. Then I wonder about details... It seems some kind of scheduled
browsing for refcounts is needed or is there something better?

It depends on the implementation, for example each kfree() may check the
reference counter and return page to the allocator when it is really
free. Since page may contiain multiple objects its reference counter may
hit zero someday in the future, or never reach it if data was not freed.
