What exactly is "clogging up memory" that everyone here complains about? I can understand if Chrome is using 6 / 8gb of your ram and you are simultaneously running photoshop and it can't grab any memory due to Chrome, but is this the case?

Shouldn't Chrome use as much RAM as it can to ensure speedy performance provided its not starving out any other applications?

I have little experience in writing desktop applications & memory management in an environment of this nature. Genuinely curious what the normal practice is.

Edit: To clarify, I am assuming the memory growth is not due to any sort of leaks :)
