If the minimal "reserved stack space" per thread is 4K, than a million threads would consume about 4GB of memory. That's not quite feasible in a 32-bit address-space. Would most threads run with even less than 4K of reserved stack space?

Using a 4k minimum was just one of the possible implementation strategies. It looks like there are several ways to get it much, much lower.
