Re: ihash & qhash help

ihash is used for data structures that are designed explicitly for
use with ihash.  These data structure will contain a link (of type
ihash_entry<>) to another object of that type which ihash will use when
building the hash table.  The i stands for internal, I believe.

qhash is use for data types that don't know they're being hashed, such
as str and int.  I believe that it's implemented in terms of ihash by
wrapping these data types in a structure containing an ihash link.

Look in the SFS source tree at sfscd/sfscd.[Ch] for examples of both.
