It's obvious that most of those random crashes are caused by memory starvation. They should have all the telemetry they need to understand and fix it, if only by popping up an error message saying 'Not enough memory to render this page' or even Safari's maddening version of the same message ('A problem occurred with this web page so it was reloaded.')

The only explanation is that they don't give a crap. Very frustrating.

Reading the bug thread cited above, it may even be a case of, "I was able to get Chrome to crash under similar circumstances, therefore it is conforming behavior. WONTFIX."
