high priority thread contains an infinite loop

[rvan]

Hi,

Assume there are 3 threads N1, N2, N3.

in N1
{

....
while(1)
{

}
}

when the thread N1 got the time slice, it started executing the infinite loop..
Note:there is no condition inside the while(1) to end the infinite loop
I heard that some RTOS will solve this problem helping the thread to come out the loop.
If so, what is the logic behind that? and where exactly it will be used.
Can anyone comment on this?

Thanks
