OK, so say I have a set of 25 instructions that are declared as being
able to run in parralel running on Tukwila.

The first 6 go in right away.  Does this mean that if slot #4 finished
executing first, then the 7th instruction will go to slot #4 ? before
the rest of the original 6 has finished executing ?

Or does it wait for all of the original 6 to finish before loading the
next 6 in ?
