Isn't that an unfair comparison though? VS is always in memory and it
knows what files you've changed via whatever means whereas bjam has to
startup, read a whole bunch of files, unserialize(?), execute stuff,

What that really means is we need something like a bjamd :)

Thanks for giving me something to think about atleast.
