Speed improvements and code restructuring
dr
Keep pushing hunks of code in circles and it almost looks like you're 
still accomplishing something.  

Minor speed enhancements by eliminating an allocate/free per packet and 
returning to a single statically allocated buffer for the main packet
stream.  It's like we never left.

Restructured timer code from a group of functions and globals into a 
real class.  This buys absolutely nothing in terms of speed, performance,
or size, but it makes the code a little nicer.
