An earlier version of the wordhash code actually did this. I have sent it to Clint
for testing.  Rather than allocating blocks for structs and 
strings from the same buffer, as the current code does, the original code maintained separate
buffers for the hashnode_t struct and for strings.

I'd much rather let the compiler take care of alignment whenever possible. Manual intervention of this
sort could be dangerous since different compilers may require different ways of doing this.
