Thread local storage IS "global" per thread though, instead of 
per process which "global" is in other languages.

The stack, is... well the stack and has nothing to do with the 
thread local storage. Although each thread has their own stack, 
else threads would have to wait for each other every time 
something was pushed or popped.

Thread local storage is a bit more complex though and very 
different than regular heap allocations.
