现在看起来不是“偶尔”，所以我有必要弄清楚问题的原因。
以下是SocketConnection建立到远程的连接之后调用的一个线程函数。能讲解一下么？
procedure TTransportThread.Execute;
procedure SynchronizeException;
var
SendException: TObject;
begin
SendException := AcquireExceptionObject;
if Assigned(FTransport) and (SendException is ESocketConnectionError) then
FTransport.Connected := False;
PostMessage(FParentHandle, THREAD_EXCEPTION, 0, Integer(Pointer(SendException)));
end;
var
msg: TMsg;
Data: IDataBlock;
Event: THandle;
Context: Integer;
begin
CoInitialize(nil);
try
PeekMessage(msg, 0, WM_USER, WM_USER, PM_NOREMOVE);
ReleaseSemaphore(FSemaphore, 1, nil);
try
FTransport.Connected := True;
try
Event := FTransport.GetWaitEvent;
while not Terminated and FTransport.Connecteddo
try
case MsgWaitForMultipleObjects(1, Event, False, INFINITE, QS_ALLINPUT) of
WAIT_OBJECT_0:
begin
WSAResetEvent(Event);
Data := FTransport.Receive(False, 0);
if Assigned(Data) then
begin
Data._AddRef;
PostMessage(FParentHandle, THREAD_RECEIVEDSTREAM, 0, Integer(Pointer(Data)));
Data := nil;
end;
end;
WAIT_OBJECT_0 + 1:
begin
while PeekMessage(msg, 0, 0, 0, PM_REMOVE)do
begin
if (msg.hwnd = 0) then
case msg.message of
THREAD_SENDSTREAM:
begin
Data := IDataBlock(msg.lParam);
Data._Release;
Context := FTransport.Send(Data);
if msg.wParam = 1 then
begin
Data := FTransport.Receive(True, Context);
Data._AddRef;
PostMessage(FParentHandle, THREAD_RECEIVEDSTREAM, 0, Integer(Pointer(Data)));
Data := nil;
end else
PostMessage(FParentHandle, THREAD_SENDNOTIFY, 0, 0);
end;
THREAD_REPLACETRANSPORT:
begin
FTransport := ITransport(msg.lParam);
FTransport._Release;
end;
else
DispatchMessage(msg);
end
else
DispatchMessage(msg);
end;
end;
end;
except
SynchronizeException;
end;
finally
Data := nil;
FTransport.Connected := False;
end;
except
SynchronizeException;
end;
finally
FTransport := nil;
CoUninitialize();
end;
end;
