I'm trying to do this:

  mbx.km_version=KSE_VER_0;
  mbx.km_func=uc_1;
  mbx.km_stack.ss_sp=stack_1;
  mbx.km_stack.ss_size=SIGSTKSZ;
  mbx.km_stack.ss_flags=SS_ONSTACK;

  ret=getcontext(&(thr_mbx.tm_context));
  printf("getcontext %d\n",ret);

  thr_mbx.tm_context.uc_link=NULL;
  thr_mbx.tm_context.uc_stack.ss_sp=thr_stack_1;
  thr_mbx.tm_context.uc_stack.ss_size=SIGSTKSZ;
  thr_mbx.tm_context.uc_stack.ss_flags=SS_ONSTACK;
  makecontext(&(thr_mbx.tm_context),func,0);

  thr_mbx.tm_uticks=10;
  thr_mbx.tm_sticks=0;  
  mbx.km_curthread=&thr_mbx;
  ret=kse_create(&mbx,0);
  do
   {
    ++i;
   }while(1);

And never got upcall. (But if I put printf in the loop I got the
upcall).

Thanks,
Sergey.
