If you'd like to go that way anyway, I would suggest 1MB as a starting

I understand the desire for caution. But I was hoping maybe we could
experiment with 4mb in trunk for a while? We could change it to 1mb--or
even 256k--before beta 1 if we get anxious.

malloc() you said? Arenas are allocated using mmap() nowadays, right?
malloc() and free(). See _PyObject_ArenaMalloc (etc) in Objects/obmalloc.c.
On Windows Python uses VirtualAlloc(), and I don't know what the
implications are of that.
