| 5 | meaningful on 64-bit builds on machines with a *lot* of memory, but the |
| 6 | tests are always run, usually with very low memory limits to make sure the |
| 7 | tests themselves don't suffer from bitrot. To run them for real, pass a |
| 8 | high memory limit to regrtest, with the -M option. |

| 20 | # memory they use and how much memory they need to be even meaningful. The |
| 21 | # decorators take two arguments: a 'memuse' indicator declaring |
| 22 | # (approximate) bytes per size-unit the test will use (at peak usage), and a |
| 23 | # 'minsize' indicator declaring a minimum *useful* size. A test that |
| 24 | # allocates a bytestring to test various operations near the end will have a |
| 25 | # minsize of at least 2Gb (or it wouldn't reach the 32-bit limit, so the |
| 26 | # test wouldn't be very useful) and a memuse of 1 (one byte per size-unit, |
| 27 | # if it allocates only one big string at a time.) |
| 28 | # |
| 29 | # When run with a memory limit set, both decorators skip tests that need |
| 30 | # more memory than available to be meaningful. The precisionbigmemtest will |
| 31 | # always pass minsize as size, even if there is much more memory available. |
| 32 | # The bigmemtest decorator will scale size upward to fill available memory. |
