That's odd, considering the docs say the specified stack size is the 
minimum guaranteed and it may allocate more. Yet it can still fail for 
being too small as if it can't allocate how much it really needs.

Should be fixed with commit 958301d, thanks. Increased the default stack 
size to 2MB, and it'll try 4MB and 8MB if needed, then just using the 
default if all else fails.
