os_evt_wait_* with timeout and os_dly_wait possible in one task?

Hello,

I learned from http://www.keil.com/support/docs/3008.htm:
a) It is not possible to mix the wait method os_itv_wait() and os_dly_wait().
b) It is possible to mix os_evt_wait_or(0x0001, 0xffff) (without timeout!) and os_dly_wait().
But is it possible in RTX to use os_evt_wait_or(0x0001, 100) (with timeout!) and os_dly_wait() in the same task?
e.g.:

void task1 (void) _task_ 1 {
  while (1)  {
    os_evt_wait_or (0x0001, 100);    // wait for event flag set or timeout (100 ticks)
    ...                              // some code
    os_dly_wait (10);                // wait here for 10 ticks
    ...
  }
}

void task2 (void) _task_ 2 {
  ...
  if (...) {
    os_evt_set (0x0001, id1);        // send event to task 1
  }
}

Or is it impossible because of the same timer is used for both delays in task 1?

Thanks in advance for your answers,
Norbert
