[SVHMPC] OpenMoko light web server

[Matthew S. Hamrick]

Yup.. that's a good idea. I have a philosophic issue with leaving  
request/response connections open, but I can probably get over it.  
The current jowles design assumes a single thread of execution, but  
it shouldn't be that difficult to add a ring thread and a SMS receive  
thread.
