free in sense of libc's free(3)? It's call count is close to zero.
Is mc a memory allocation intensive beast? glib allows to insert own plugs
for malloc/free:

void g_mem_set_vtable (GMemVTable * vtable);

struct _GMemVTable                                                                                                             
  gpointer (*malloc)      (gsize    n_bytes);
  gpointer (*realloc)     (gpointer mem, gsize n_bytes);
  void     (*free)        (gpointer mem);  /* optional; set to NULL if not used ! */
  gpointer (*calloc)      (gsize    n_blocks, gsize    n_block_bytes);
  gpointer (*try_malloc)  (gsize    n_bytes);
  gpointer (*try_realloc) (gpointer mem, gsize    n_bytes);

What heap object's lifetime  bothers you? There is also g_mem_chunk_* for
fixed sized objects suitable for dentries.

Would be nice to see the problem for solution.
