Summary: objects never get garbage collected when requested via ObjectSpace._id2ref

Initial Comment:
id="s".object_id
GC.start
p ObjectSpace._id2ref id

results in -> `_id2ref': 0x15add5c is recycled object (RangeError)

this is the expected behavior. the anonymous local object "s" gets garbage collected. however if i do a ObjectSpace._id2ref before garbage collection it somehow does not get recycled: 

id="s".object_id
p ObjectSpace._id2ref id
GC.start
p ObjectSpace._id2ref id

results in -> "s"
"s"

seems that _id2ref does some caching. i think it is a bug, because it seems that the objects requested through _id2ref stay in memory forever.
