Fortunately libmpdec raises MemoryError almost instantaneously, so the PR retries the affected operations with estimated upper bounds for exact results without slowing down the common case. The docs still need updating because people will still wonder why 1 / Decimal(3) freezes the Linux machine at MAX_PREC. ;) The Python implementation cannot use this approach because memory grows slowly. I'm not sure though if anyone _would_ run _pydecimal at MAX_PREC.
