It seems too dangerous/annoying to have pools error when they run out of memory. Instead, we'll make it so you can choose to make a pool resizable, where it enlarges its memory if it runs out. By default Pools aren't resizable, but the default math pool is. Also, reduce the size of the default pool from 640k to 4k.
