cool

I think that we should learn from this category speedup.

1- It seems to me that lot of the design choices which made absolute  
sense in the early life of Smalltalk
(the way system category,class category for example are managed)  
because running something
on that machines was a real challenge, now should be revised.

2- lot of small changes can make a difference. Incremental process is  
good even if there
is no problem throwing away them when a better solution arrives.

So I encourage everybody to help :)
For example the network seems a bit requiring help
