+Summary: Executing domains in different threads
+
+When creating domains from different threads, either an assert is hit or unhandled null 
+exceptions are thrown. This happens on osx ppc machines as well as osx intel machines. (I 
+haven't tested other platforms, but i presume it will behave the same)
+
+
