Re: Memory leak after closing thread.

Before I explain exactly where is the problem I will show my code:
(Platform - Windows CE 5, VisualStudio 2005)

The interesting part of source code is below:

/**************************************************************/
class classA {
        public:
        static DWORD WINAPI testingThread(LPVOID lpvoid);
        HANDLE m_hThread;
        void startthread();

};

DWORD WINAPI classA::testingThread(LPVOID lpvoid)
{
        return 1;

}

void classA::startthreadk()
{
        for(int counter = 0 ; counter < 100 ; counter++) {
                MEMORYSTATUS memInfo;
                memInfo.dwLength = sizeof(memInfo);
                GlobalMemoryStatus(&memInfo);
                DWORD dwThreadId = 0;
                m_hThread = CreateThread(NULL, 0, testingThread, this,
0,
&dwThreadId);
                DWORD dwRet = WaitForSingleObject(m_hThread,
INFINITE);
                if(WAIT_OBJECT_0 != dwRet) {
                        TRACE(_T("Something wrong !!! \n"));
                }
                int returnHandle = CloseHandle(m_hThread);
                TRACE(_T("After closing handle = %d
\n"),returnHandle);
                m_hThread = NULL;
                MEMORYSTATUS memInfo1;
                memInfo1.dwLength = sizeof(memInfo1);
                GlobalMemoryStatus(&memInfo1);
                TRACE(_T("%d Test %d\n"),counter, memInfo.dwAvailPhys
-
memInfo1.dwAvailPhys);
        }

}

/**************************************************************/

The problem is that I don't know why but sometimes (usually one per
three times)
I can see the memory leak of 4096 bytes. Why? Do I do something wrong
with closing
thread? (Of course the program without creating thread works ok).
Closehandle
always returns 1, so everything should be ok.

I will be grateful for any response.
