Using the Redstone block to create THIS (Which is in the picture) and it goes really fast then when I break the redstone block the pistons are still moving and going. Its not a visual bug because i can stand where the pistons are and no block is moving me out of the way.
Way to recreate. Make the thing in the picture then put a redstone block in front of a piston of your choice then break it.

I /think/ you are not really breaking the block, instead it becomes invisible (MC-5774).
It could have been but I placed 4 blocks in it to stop it and it didn't stop me or become visible again. I also logged out and logged back in and it was still going.
