Comment(by simonmar):

 Hmm, this is an unpleasant bit of code :-)  hardcoded constants and
 guesses everywhere.

 Could we not use something better than a hardcoded "5" for the info table
 size?  We know the size of the info table for a continuation:
 `sizeof(StgRetInfoTable)`, and add to that the maximum offset due to
 alignment.

 You could also do better than `length blocks`: the actual number of info
 tables is available.
