} I have tried this. It works just fine. Both problems lools like has been

It's a large step in the right direction.  The questions remaining are:

What is the right value for HEAPSIZE?   Mmultiplying it by 10 is was just
a quick way to test; it might be better to multiply by 8 or 16 to keep a
size that's a power of 2 for efficient byte alignment of arena blocks.
It depends on the underlying malloc implementation.

Has this really addressed the problem from 29175?  Larger blocks will
mean it takes longer for the arena list to grow, but a loop that uses
enough memory can still become pathologically slow.
