Starting animations immediately breaks syncbase values

What steps will reproduce the problem?
The attached example fails using r1241 and later with Flash 10/forceflash=true

What is the expected output? 
Green square changing to blue at 3s.

What do you see instead?
Green square forever.

See Issue 557  and r1241. - "The fix to be implemented is to start immediate 
animations right away after adding instead of waiting for the scheduler loop."

By starting animations immediately, they fire a begin event but other 
animations which have syncbase values referencing this event have not had a 
chance to add an event listener for that event.

From the attachment:
<rect  x="10" y="10" width="80" height="80" fill="red">
  <set id="a1" attributeName="fill" to="green" begin="0s" fill="freeze"/>
  <set attributeName="fill" to="blue" begin="a1.begin+3s" fill="freeze"/>
</rect>

The first animation is started immediately and fires a begin event in 
timeIntervalStarted(). The second animation doesn't get a chance to add an 
event listener (for a1.begin) until later when it performs parseParameters(). 
The second animation never starts.
