const STACK_SIZE: usize = _; // 2_088_960usizeExpand description
We want our default stack size limit to be approximately 2MB, to be safe for JS helper tasks that can use a lot of stack, but expect most threads to use much less. On Linux, however, requesting a stack of 2MB or larger risks the kernel allocating an entire 2MB huge page for it on first access, which we do not want. To avoid this possibility, we subtract 2 standard VM page sizes from our default.
