Forgot to mention that a non-thread local mark/sweep would still 
scan all thread stacks and pages like it does currently as a 
thread local could hold a pointer the the global data (ie a copy 
of __gshared, void*).

The only why I can think of to break this idea is using cast() or 
sending something to a C function that then does and adds 
pointers in global data to the thread local stuff...
