Another thread question

Lets say I have a class like this

public class MyThreadWorkerClass

public sub DoWork()
  '  do work
    Thread.CurrentThread.Abort()
end sub

end class


In this class I start the threads

public class ThreadStarter

public sub StartMyThreads()
        if threadcnt < maxThreadCnt then
            dim tWorker as new MyThreadWorkerClass
            dim t as new Thread(AddressOf MyThreadWorkerClass.DoWork)
             t.Start()
             threadcnt += 1
        end if
end sub

end class


My question is this.  When the thread aborts itself, does that kill the thread and tworker object (set them to nothing) or does this leave objects hanging, eventually leading to a memory leak?

How would you set the objects to nothing otherwise when the thread finishes?
