The cmp() / PyObject_Compare() removal patch is almost done. With some 
help I can finish it until Tuesday evening. We can have another release 
by Monday Dec 15th. Python 3.0.0 has some defects that should be fixed 
before people are spending their Xmas holidays with 3.0. The defects include

* cmp(), PyObject_Compare() and frieds
* global/nonlocal shortcuts (global x = 0) aren't working
* unnecessary slowdown of read() due slow buffer resizing.

An early 3.0.1 release makes it possible to sync 2.6 and 3.0 relases 
again. If we release it now we can have an combined release of 2.6.2 and 
3.0.2 in two months from now. Two months are quite some time to fix the 
performance issue of the new IO library.

If Guido and Barry are fine with a lax policy on performance fixes we 
can integrate more tweaks. I believe performances patches were 
considered as features in the past. For this reason they weren't allowed 
for minor releases. Mark's work on long integer optimizations and json 
speedup are good candidates.
