我试图了解如何在Mac OS X中的该过程中对进程进行资源限制(我有10.6).在CentOS上,以下测试程序(python3.3)按照我的预期工作:

import resource
import signal

def confirm(prompt, instructions='(y)es or (n)o only, please.'):
    while True:
        ok = input(prompt)
        if ok in ('y', 'ye', 'yes'):
            return True
        if ok in ('n', 'no'):
            return False
        print(instructions)

def handle_cpu_soft_limit(signal, frame):
    print('CPU soft limit reached.')
    if not confirm('Do you want to continue anyway? (y/n): '):
        raise ResourceWarning()

def long_function():
        a = 0
        while True:
            a += 1
            a -= 1

def main():
    # set soft limit to 1 second, hard limit to 5 …
