+ On the GranSim/GUM specific parts of the InfoTables (GRAN/PAR):
+
+ In both GranSim and GUM we use revertible black holes (RBH) when putting
+ an updatable closure into a packet for communication. The entry code for
+ an RBH performs standard blocking (as with any kind of BH). The info
+ table for the RBH resides just before the one for the std info
+ table. (NB: there is one RBH ITBL for every ITBL of an updatable
+ closure.) The @rbh_infoptr@ field in the ITBL points from the std ITBL to
+ the RBH ITBL and vice versa. This is used by the RBH_INFOPTR and
+ REVERT_INFOPTR macros to turn an updatable node into an RBH and vice
+ versa. Note, that the only case where we have to revert the RBH in its
+ original form is when a packet is sent back because of garbage collection
+ on another PE. In the RTS for GdH we will use this reversion mechanism in
+ order to deal with faults in the system.
+ ToDo: Check that RBHs are needed for all the info tables below. From a quick
+ check of the macros generated in the libs it seems that all of them are used
+ for generating THUNKs.
+ Possible optimisation: Note that any RBH ITBL is a fixed distance away from
+ the actual ITBL. We could inline this offset as a constant into the RTS and
+ avoid the rbh_infoptr fields altogether (Jim did that in the old RTS).
