I found the code at:
http://www.cs.chalmers.se/~rjmh/QuickCheck/QuickCheckM.hs
The only deconstructor there for PropertyM requires a "run" function
of type m Property -> Property. For IO, run is unsafePerformIO.

I'd like to use QuickCheck on IO code. For instance, I'd like to
check a property of type String -> IO Bool.
Using unsafePerformIO seems straightforward (though I haven't written
the code, so I may be wrong about that) and it might be possible to
make a solution involving unsafeInterleaveIO work
