Abstract
A computer-implemented method, computer system, and memory for performing a fork operation of a parent process is provided. The parent process includes one or more threads, each having a kernel stack. The method includes the steps of locating the kernel stacks in a first memory location (e.g., segment 1) if the parent process is multi-threaded, in response to an initiation of a fork by a calling thread, switching the kernel stack of the calling thread to a second memory location if the parent process is multi-threaded, and copying the second memory location (e.g., segment 2) to create a child process.
