Problems with multithreading - HELP [modified]

First of all, let me state that I am new to multithreading. I am working on a project that makes constant queries to a network device via a tcp connection. These queries can generally take about a third to a half a second to complete. As it stands I am creating several (4-5) separate threads that loop and make queries then report the result data to my main thread. Each thread maintains it's own tcp connection to the device. Each of the threads is set to sleep for an entire second each loop cycle, each of the threads is set to lowest priority. Yet CPU usage is through the roof. And i'm using a modern 3+ ghz machine. Why is my application eating up so much CPU time? Is there a cure for this, am I doing something wrong? Please help. -- modified at 19:01 Friday 25th August, 2006

Fixed. Problem had nothing to do with multithreading. Code was getting stuck in a while loop. My own dumb fault. A single call to System.Threading.Thread.Sleep inside the while loop brought CPU usage down from 85-100% to 12-18%.
