Making this a documentation problem.
Static variables just can't hold references of any kind.
For objects it's avoidable with ZE2 because of the new object model.

Another unfortunate bug with references appears to be that statics
holding references inside methods are actually transient, and a
reference will be lost.
For example, calling the following code several times will initialise
$db and return every time with a new instance.
function &getInstance()
{
static $db;
if (!isset($db)) {
$db =& new FS_DB();
}
return $db;
}
whereas the following will give true singeton behaviour and initialise
just once, as expected.
function &getInstance()
{
static $db;
if (!isset($db)) {
$db = new FS_DB();
}
return $db;
}
