Well.. dlmalloc (and Linux glibc which is based on dlmalloc) only
releases free memory to the OS from the top. So if an application does
something like
   allocate some memory
   allocate some more memory
   free the first allocated memory
then this memory is not releases back to the OS until the application
also frees the second allocated memory area.

The memory might eventually get released. Until then it is automatically
reused for future memory allocations.

Probably no need to worry, unless you are extremely short on memory
which is not good idea if your intent is to accelerate things..
