> Locator can't start if a few hundred clients already started.
> Steps to reproduce:
> 1. Start Locator
> 2. Start 300 Geode clients
> 3. Stop Locator
> 4. Start Locator again
> Observe 100% CPU load and after some time Locator app crashes with timeout
> exceptions in the log.
> The problem is in the method
> org.apache.geode.distributed.internal.InternalLocator.PrimaryHandler#processRequest
> handlerMapping doesn't have handlers for LocatorListRequest and
> ClientConnectionRequest requests on Locator startup and in this case work
> code part with condition 'if(giveup == 0)'(InternalLocator:1185)
> Pause Thread.sleep(1000) works only on the first iteration and after that
> giveup>0 and CPU just spends resources on cycle execution without any pauses.
> Call Thread.sleep(1000) should be after if(giveup>0) condition block. It
> will be called on each iteration in this case.
