does OS X kernel share any code with FreeBSD kernel's memory management
subsystem ?
IMHO no. OSX is somehow-microkernel based, they did take things from
FreeBSD but not this IMHO.
anyway - who cares
Something is deeply broken in OS X memory management
most importantly networking but certainly not memory subsystem.

The simple answer is no. A more complex answer:

If you really are having a problem with FreeBSD you are going to have to do
a lot better than this in terms of providing some data points which define
the problem. I am in agreement with Adam here: either you can work the
problem or you can troll. I don't see any indication yet of any real
is relatively new. My guess is that if there is a problem it's ZFS
specific. If it were a more general problem I think we'd see a lot more
complaints, whereas ZFS already has a reputation for needing lots of
memory.
you may precisely set up a limits of memory that ZFS would use at most. or

The simple answer is no. A more complex answer:

The related implementation in FreeBSD seems to have a similar problem:
NetBSD users have also reported that UVM’s im- provements have had a positive
