Python 内部维护一个数值N(sys.getcheckinterval() ),模拟内部的“软件中断”,当执行了某个线程的N 条指令之后应该立刻启动线程调度机制,因为 Python 中的线程实际上就是操作系统所支持的原生线程,故下一个被调度运行的线程由操作系统来选择。 p394:Python 线程的创建...

On examining the process memory usage, it continuously leaks, we are doing the following command to check(Note that the leak is slow and ultimately linux kernel oom kills the process.) while true; do ps -o pid,user,%mem,command ax | sort -b -k3 -r | grep <pid> ;date ; sleep 5...
