I barely remember that we had discussion over the email about how we will implement this. I think it'll be set through mallopt, right? Besides, I'm not sure if we have agreed to implement it like this. For example, can we just grow the buffer when it meets certain condition? Or can't we use the env variable to set the size before the start of debugging app?
