Not free after CreateToolHelp32Snapshot

I call Snap := CreateToolHelp32Snapshot(TH32CS_SNAPPROCESS, 0);
after I try free memory by CloseHandle(Snap);
This I use to my program which can show list and process and kill them.
Every second list is refresh and calls CreateToolHelp32Snapshot - CloseHandle
On Windows memory in near constant,on ReactOS rapidly memory leak.
I attach binary and source test program where every 50 ms is called CreateToolHelp32Snapshot - CloseHandle
