Weird.

This is the output to expect:
-------------------------------------------------------------------------------
PYBENCH 2.0
-------------------------------------------------------------------------------
* using Python 2.4.2
* disabled garbage collection
* system check interval set to maximum: 2147483647
* using timer: time.time
Calibrating tests. Please wait...
Running 10 round(s) of the suite at warp factor 10:
* Round 1 done in 6.627 seconds.
* Round 2 done in 7.307 seconds.
* Round 3 done in 7.180 seconds.
...
Note that the calibration step takes a while.
Looking at the code, the only place where it could
hang (because it's relying on a few external tools)
is when fetching the platform details:
def get_machine_details():
 import platform
 buildno, builddate = platform.python_build()
 python = platform.python_version()
 if python > '2.0':
 try:
 unichr(100000)
 except ValueError:
 # UCS2 build (standard)
 unicode = 'UCS2'
 else:
 # UCS4 build (most recent Linux distros)
 unicode = 'UCS4'
 else:
 unicode = None
 bits, linkage = platform.architecture()
 return {
 'platform': platform.platform(),
 'processor': platform.processor(),
 'executable': sys.executable,
 'python': platform.python_version(),
 'compiler': platform.python_compiler(),
 'buildno': buildno,
 'builddate': builddate,
 'unicode': unicode,
 'bits': bits,
 }
It does run fine on my WinXP machine, both with the win32
package installed or not.
