Description
IndyPeerImpl.pas register a list of PeerFactory in initialization section:


initialization
  PeerFactory.RegisterPeer(IPImpId, IIPPeerProcs, TIdProc);
  PeerFactory.RegisterPeer(IPImpId, IIPStack, TIdStackPeer);

  PeerFactory.RegisterPeer(IPImpId, IIPHTTP, TIdHTTPPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPSSLIOHandlerSocketOpenSSL, TIdSSLIOHandlerSocketOpenSSLPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPTCPClient, TIdTCPClientPeerIP);
  PeerFactory.RegisterPeer(IPImpId, IIPBasicAuthentication, TIdBasicAuthenticationPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPX509, TIdX509Peer);

  //server specific peers
  PeerFactory.RegisterPeer(IPImpId, IIPServerIOHandlerSSLOpenSSL, TIdServerIOHandlerSSLOpenSSLPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPHTTPServer, TIdHTTPServerPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPSchedulerOfThreadPool, TIdSchedulerOfThreadPoolPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPTCPServer, TIdTCPServerPeer);
  PeerFactory.RegisterPeer(IPImpId, IIPTestServer, TIPTestServerPeer);

There is no way to free the items register PeerFactory (or there is no way to UnRegister).

This make application that use dynamic package loading cause problem when IPIndyImpl.bpl was loaded and unloaded few times.
