They use the TCL hash tables.  They're opaque from scheme but they
probably could be modified to be more transparent.  You can read them
& write them to/from files using, e.g. hash-table->list, which
requires rehashing.  Other than that, I'm not so familiar with the
internals - I haven't read the code carefully.
