#Is it intended that i2c.close also closes the associated gpio channels ?

If I create a i2c bus device, use and close it again, then a repeated creation reports an ALREADY_IN_USE exception error.

Typically we only close pins (or other objects) if we have allocated them. So the I2C bus is not supposed to close the pin itself.

We might not be fully consistent with that though, but closing should be idempotent and thus closing again should be fine. (Again, I think we are not 100% consistent there yet, but are working towards it)
