From Raymond Hettinger, submitting here to keep track of for 
NeedForSpeed sprint.

Here are some customizations to your Python build:
 
First, make sure that WITH_TSC and WITH_THREAD are not defined in the 
build.

Then, attached diff to disable the tracing code, remove NOPs, speed-up 
absolute jumps, and increase the signal check interval.

Okay, now I checked the box "upload and attach file".  Thats a terrible UI.

Assigned to Raymond.  Raymond is there something of general
use here?  As a standalone patch, it sucks ;-)

Sorry, all of these are useless for the general distribution.

* Increasing the ticker rollovers will give a tiny speed-up but would hurt the responsiveness of multi-threaded applications.

* The tracing functions are needed in the general distribution and should not be shut-off.

* The NOP case is a fail-safe; not essential, but not detrimental either.  The peephole optimizer introduces NOPS and then clears them out.  If someone makes a change leaving them in or if they are generating their own bytecode, we don't want the eval-loop to fail.

* The JUMP_ABSOLUTE step needs to make a full trip through the eval-loop or else it won't be possible to break out of a "while 1: pass".
