Singularity: Reading Question


Ren, a rogue SIP, has managed to break the memory independence invariant by obtaining a pointer to an object in another SIP. Thankfully, Ren isn’t entirely evil: it will only read from the pointer that it’s obtained.

What can go wrong if the garbage collector in Ren assumes that the object the pointer points to belongs to Ren? What can go wrong if the garbage collector in Ren ignores the pointer?


Submitting


Local Stanford students should write up their response on a sheet of paper that includes their name. The sheet of paper with the response should be submitted immediately before lecture.

SCPD students should write up their response in a text file named response.sing.txt and upload it via the submission and grades page. You’ll need to sign in with your SUNetID to access the page. Responses will be accepted until one week after the corresponding paper’s lecture.

In either case, the response should be short, likely only a pithy paragraph in length.
