I wrote this test with drj when we were convinced there was
|
|
a bug in pool scanning because of ScanStateSetSummary setting
|
|
unfixed to be potentially bigger than the segment summary. But
|
|
it turned out not to be a problem, 'cos ScanStateSetSummary is
|
|
called (at least by AWL) _before_ scanning is done.
