What size do you call mid-sized ?

You could write your own malloc functions my_malloc(),
my_free() and my_collect_garbage() and only make one call
to the original malloc() at startup, and free() at exit.

There also exist several PD packages that do just this.
I don't have any pointers where to get these, however...
