Below are the changes since Tor 0.3.1.7.
o Major feature (scheduler, channel):
- - Clients and relays now use new schedulers to decide which circuits
- should deliver cells first. The first type is called "KIST"
- ("Kernel Informed Socket Transport"), and is only available on
- Linux-like systems: it uses feedback from the kernel to prevent
- the kernel's TCP buffers from growing too full. The second new
- scheduler type is called "KISTLite": it behaves the same as KIST,
- but runs on systems without kernel support for inspecting TCP
- implementation details. The old scheduler is still available,
- under the name "Vanilla". To change the default scheduler
- preference order, use the new "Schedulers" option. (The default
- preference order is "KIST,KISTLite,Vanilla".)

Matt Traudt implemented KIST, based on research by Rob Jansen,
John Geddes, Christ Wacek, Micah Sherr, and Paul Syverson. For
