Hi, after finished building the ecos1.3.1 on Redhat 
linux6.1(target is pc x86),I use gdb stub and the example twothreads.c to 
test.
>From the doc ument and the code of 
kernel, I think the threads of same priority should switch by 
timeslice .But after comment the sentence in twothreads.c as 
followed:
          
cyg_thread_delay(200);
I find no switch.Who can tell me why? I think the switch of 
thread invoked by dsr of real time clock interrupt.Is that right?
  Thanks a lot.
