[Tutor] 6x6 word square solver too slow

[R. Alan Monroe]

Any bright ideas on how I can speed this up? It seems REALLY slow for
as little as it does.

I'm trying to generate word squares like this:
P R E Y
L A V A
O V E R
T E N D
except 6x6 rather than 4x4.

In particular, the profiler indicates that {method 'join' of 'str'
objects} is eating an awful lot of time (odd...), but I'm having a
brain cramp trying to think up a workaround or alternate approach.

The required sixwords.txt file can be gotten here:

(wasn't sure if people would complain about a 43K attachment or not)
