AFAIK, no you don't. malloc uses sbrk to get memory from the DPMI server. It
gets *that* memory in powers of 2 to reduce overhead, but then parcels it
out to malloc calls as it's needed. So each structure should just be using a
34K block, it's just that malloc grabbed some extra which will be given to
the next request.

What makes you think you are losing memory?
