Subprocess timeout

[George Sakkis]

I'm trying to use a threaded timeout decorator (http://
aspn.activestate.com/ASPN/Cookbook/Python/Recipe/483752) to spawn a
subprocess with a timeout. On a linux box runnning python 2.5 I get
"OSError: [Errno 10] No child processes" on wait(); running the same
program on a different box (again linux) with python 2.4 doesn't throw
an exception. Here's a sample snippet:

import os
from subprocess import Popen,PIPE

@timelimit(3)
def f(cmd):
return Popen(cmd, stdout=PIPE)


p = f('ls')
print os.getpid(), p.pid
# the next line raises OSError on 2.5 but not on 2.4
print os.waitpid(p.pid, 0)

What gives ?
