FreeBSD vice OS X memory management

Hi,

does OS X kernel share any code with FreeBSD kernel's memory management
subsystem ?

Something is deeply broken in OS X memory management

One of the problems that caught my eyes was inactive memory reclamation.
I remember some time ago there was a thread here with similar topic.
