------- Additional Comments from Adele Peterson <adele at apple.com>
I'm still running tests, but I'm posting this for review anyway.  I set a
breakpoint and verified with this patch, I won't hit the validity checks at all
while running the PLT.	The tests I'm constructing now involve adding and
removing valid/invalid pseudostyles and making sure that style sharing happens
in the right circumstances.
