 ==============================
-* implement message passing built-ins
-* add --deadlock_prevention:on|off switch? timeout for locks?
-* built-in serialization
+* test threads on windows; thread analysis needs to be even more restrictive!
+* implement message passing built-ins: channels/queues
+* outOfMem hook; 0 over-head for hello world program :-)
+* bug: {:}.toTable[int, string]()
