Jake Burkholder 34aef253aa Fix obscure problems with vfork where part of the parent's stack could be ... clobbered by the child. This is more complicated than usual because the window that could get clobbered is pushed in kernel mode, so a lot of registers would have to be saved in other registers in userland and we don't have enough. What we do have is space in the pcb to temporarily store user windows that were spilled in kernel mode, but could not be immediately stored to the user stack. So we copy in the parent's topmost window and save it in the pcb, and arrange for it to be copied back out when the child is done frobbing the stack. Reviewed by: tmm		2002-03-04 05:07:22 +00:00
