the current SVN snapshot (this):

It appears as if the import mechanism took a hit between the
versions.
The NFS sprint results are also visible.
A little disturbing is the slow-down for Python function calls
and the built-in method lookup. Did anything change in these parts
of the interpreter ?
This is the machine I used for running the pybench:
 Timer: time.time
 Machine Details:
 Platform ID: Linux-2.6.8-24.19-default-x86_64-with-SuSE-9.2-x86-64
 Processor: x86_64
