Yes, but you might want to limit a single client to a process and 
limit the thread count, for isolation and simple load balancing. 
But I am not sure what the use scenario is...

Usually limited. Correctness is more difficult to prove with high 
levels of parallelism... And you can use FPGA...

That is odd. Parallell algorithms usually comes with overhead.

You meant parallell? (super scalar just means that a single core 
has multiple execution units, a single core can schedule multiple 
instructions at the same time)

Well, if you need more than a single thread to update a gui (sans 
rendering) then you've picked the wrong layout strategy in my 

I dont want the gui to suck up a lot of cpu time and polute the 

And yes I think layout engine API as well as styling are very 
important to do well, even if it incurs overhead.

I'd rather have simple layout if that is the bottle neck...

Layout engine design a styling engine design is really the 
biggest challenge. You cannot design the architecture before 
those two are known.  Also embedded have fixed screen 
dimensions... No need for real time resizing...

What is missing is a good detailed description of primary use 
scenarios. Without that no rational design decisions can be made.

That is software engineering 101.

Without that we will just talk past eachother making different 

What is certain is that the long page browser layout engine isn't 
very well suited for fixed dimensions...
