Yes, it appears to have been pulled.
LT: Inadvertently installed it early yesterday AM without checking for MS documentation (as I usually do for all patches before installing), (Bummer). That said, no apparent ill effects, as of now.
DT 1: Found this thread before installing it, so opted to wait, but did not hide it (I did install the other 3 patches). As of 7:30 last night, it was still listed as an "important" update that was available, with the customary WU alert icon in the system
tray. At 8:30 last night, WU automatically checked for updates and <poof!> KB976902 was gone from the list. WU now says I am up-to-date, with no available important updates, and no WU system tray notification icon.
Vanishing black hole, indeed!
Thanks to all for helpful input and info (in the glaring absence of information or documentation from Redmond!),
