creating every thread, starting every thread, then joining every thread was
not 
working.  I continuously received exceptions and timeouts when performing
many gets


My thinking was that i need to limit the ammount of threads connection
manager is using.
So i decided to through in a executor thread that will only dispatch so many
threads depending
on if they're still active or not it continues on to create new threads.

My  exe.awaittermination was set to 30 seconds so my executor would run for
30 seconds 
then kill all threads its started before it finished. I noticed this
yesterday, and changed the 
awaittermination code.  

I realize i can do something more elegant but for now it solved my problem
and httpclient 
seems to be working as it should for me.

So basically it was my fault nothint to do with httpclient






        	ExecutorService exec = Executors.newFixedThreadPool(500);
           
            try {
				for (int j = 0; j < dmdl1.getRowCount(); j++) {
					exec.execute(new GetThread(httpclient, new HttpGet(dmdl1.getValueAt(j,
2).toString()), j + 1, dmdl1, (ThreadSafeClientConnManager) cm));
				}
			} catch (Exception e) {
				// TODO Auto-generated catch block
				System.out.println("THREAD PROBLEM");
			}
            exec.shutdown();
            /* The tasks are now running concurrently. We wait until all
work is done, 
			 * with a timeout of 50 seconds: */
        
            boolean b = exec.awaitTermination(1, TimeUnit.DAYS);
			/* If the execution timed out, false is returned: */
			System.out.println("All done: ");// + //)b);
