-Hashing doesn't improve the result of grob property lookup, at least
-not with naive hashing. It is possible that the overhead of the
-scm_hash* functions take too much time. One way to solve this is by
-using vector accesses directly, and precompute the hashvalues, similar
-to CACHE_SYMBOLS. That option could only cause slowdowns if the hash
-tables produces weird cache-line trashing.
-
-Second option: we could index immutable props in a hash tab as
-well. This only takes space, since they are immutable no updates are
-needed. This does take a lot of space, since we must duplicate the
-alists (but not the entries).
