bitshift shift has lower precedence than division, meaning in MemoryUsageExceededError.init we end up trying to bitshift a float, which is nonsense (as the expression in the f-string gets interpreted as (threshold / 1) << 20, and the result of all divisions in python is a float). Add some parenthesis.

We cannot just write this as threshold >> 20, as we care about the fractional part.
