acid/kernel: for stacktraces, try to use context from error stack when process is not sleeping when a process state has not been saved (Proc.mach != nil) then the contents of Proc.sched should be considered invalid. to approximate a stacktrace in this case, we use the error stack and get a stacktrace from the last waserror() call.
