[Haskell-cafe] Unsafe IO and Wash

On a related note, Wash seems to be preserving all sorts of unnecessary
"state" from previous screens a user visited.  I don't understand why it
doesn't pass only the parameters to the next screen; that should be
easily determined to be all that is necessary.

On that same topic, I've used Wash's unsafe_io some places with no ill
effects.  (Note that this has no relationship to unsafePerformIO, which
is a different beast entirely.)  Can anyone tell me why unsafe_io in
Wash is unsafe, and in which situations it could blow up in my face?
