  What is this patch? Are you refering to the asynchronous focus change?

  I enabled it, and it does make a little difference, in that the
  input locking periods tend to get shorter, but not always.

  I could imagine a complex application with multiple windows
  interacting with each other malfunctioning if we suddenly changed the
  PM message processing to async, but most well written applications
  shouldn't suffer, and those little apps that have only one window and
  one message queue will be totally unaffected.

  Furhermore, it could be made user selectable, so if there were an
  application that simply MUST use a SIQ, than it could be switched on
  before you run it, and off after.
