There's no + symbol on the new tab icon in Chrome 17

Those of us who visit HN and Reddit front pages opening lots of links to read later will find all of them sharing the same process. In Chrome 17 they set the maximum memory use for the process to 1GB. As usage approaches that amount the garbage collector runs and will eventually hit 100% CPU time since it will not find anything to free but the process has run out of memory.
In Chrome 16 the limit was 2GB which took at least twice the effort to hit, but still was just as annoying. There is no way of fixing this problem I can find (the --process-per-tab option doesn't do it). (You can kill the process and/or reload the browser but that loses state in pages.)
I'm on a 64 bit machine with 16GB ram and 8 cpu cores, so having the browser stuck at 6% of my ram and 12% of my cpu is annoying.
my favorite justification of removing the plus sign is that "it's too jarring".
Lookin closer the button looks like an "small empty tab", so maybe the designers decided that the + was redundant?
Usability first.
In addition to her own confusion, add mine when I'm telling her on the phone to look for the "plus" icon at the right, and it's no longer there.
I've had similar issues with Google's Calendar product UI, for example. They just change it, and adopt non-standard and to my mind often rather unobvious controls -- users be damned.
(I won't start on my parents' use of Android phones...)
TL;DR: You want market share, you'd better make sure that market can figure you out.
I'm pretty sure Opera lets you get rid of it, but I can't really remember.
