+ Rewrote exchange routines to allow
+ o General tile <-> tile connectivity.
+ o TAMC reverse mode flag ( is this really needed? )
+ o Variable width overlap and exchange region widths.
+ o Hooks for sharing data via DMA, Arctic, Memory Channel, 
+   shmput/shmget, VIA, SYSV shmem and every other cool 
+   communication method.
