I don't have much time, so I apologize for the brevity.
I have noticed, quite by accident, that Google Chrome may have a memory leak. I left an instance running for a week or so (maybe longer, maybe shorter) and found it consuming nearly 1GB in private memory for its single tab. Of course, since Chrome forks its process, it is absolutely a single tab. This tab is Google Analytics Real Time view, so any bug on the web page would again be in Google's court.
UPDATE: This slow memory leak *does* persist in the latest version. It will eventually grow and consume all available virtual memory if left unchecked. The factors that influence this memory leak are unknown at this time. Leaving a single Chrome instance/tab open with Google Analytics Real Time view can reproduce it.
UPDATE2: After getting independent verification in the comments, I reported this bug to Google, so hopefully it gets fixed. It is a surprise anyone noticed, or verified.
UPDATE3: Verified more times since the original Feb 2 report. Bug tracker on Chromium is this issue: http://code.google.com/p/chromium/issues/detail?id=112424 - Continues as of 08/01/2012 (latest build not in screenshot).
UPDATE4: Bug VERIFIED by Google, moved for Triage. New (merged) issue: http://code.google.com/p/chromium/issues/detail?id=140028
