Today, I cheated a bit, and used my Release Assistant super powers, and removed from testing 2 packages with long standing RC bugs and no activity from the maintainers:

See my hint file:

 #20080319
 # 467096
 remove traverso/0.42.0-1
 # 243363
 remove xcruise/0.30-8

edit: twinkle removal was a bit hasty, I totally missed that the bug wasn't RC from the beginning. And as a second thought I'm not either sure it's really RC.
