You're going to laugh but right now it's down to a bit of Ruby and a  
nifty C extension.  Seriously.  No need yet of much more than some  
threads that crank on output, a parser (in C) that makes a hash, and  
a way to quickly lookup URI mappings.  The rest is done with handlers  
that process the result of this.  It may get a bit larger than this,  
but this core will probably be more than enough to at least service  
basic requests.  I'm currently testing out a way to drop the threads  
in favor of IO.select, but it looks like that messes with threads in  
some weird ways.

Once I figure out all the nooks and crannies of the thing then I'll  
do a more formal design, but even then it's going to be ruthlessly  
simplistic.
