38 * Push thread info onto the new thread's stack
40 movl 12(%ebp), %esi # get stack addr
43 movl 20(%ebp), %eax # get start argument

51 * Prepare and execute the thread creation syscall
60 * Check to see if we are in the parent or child
72 * If we are in the child (new thread), then

74 * returns, then call __exit.
91 * Branch here if the thread creation fails:
