usleep

["Lee Chin" <leechin@mail.com>]

I would think the following code would wait for 1 second each itteration before printing hello, but it waits way too long.  Replacing the for loop body with a 
usleep(1000000) works great... what am I missing here?

Thanks
Lee

#include <unistd.h>

int main()
{
    while (1)
    {
        int i;

        printf("hello\n");
        for(i = 0; i < 50; i++)
        {
            usleep(1000);
        }

    }

}
