Approach 1: Nogc thread can hold references to the gc heap that 
is known to be under bookkeeping or that is reachable from 
objects that are under book keeping. No need to scan the @nogc 
thread then.

Approach 2: separate scan and freeing in the GC by pushing 
collected item onto a list of pending objects that are waiting 
for @nogc to complete an iteration before they are put on the 
freelist. This should work for standard culling.
