Class `PhabricatorPolicyAwareQuery`, on line 220:
```
if ($need) {
$this->rawResultLimit = min($need - $count, 1024);
} else {
$this->rawResultLimit = 0;
}
```
When querying for events for user availability, `rawResultLimit` is 0, resulting in unexpected results. This task is a placeholder to figure out if this is a problem, if the current workaround in `PhabricatorCalendarEventQuery` around line 177 is okay, or if there is a better fix.
