You may find that you when calling CreateToolhelp32Snapshot that you must specify SnapshotFlag.NoHeaps in addition to any other flags or you will get an invalid handle and an "Out of Memory" error (ERROR_NOT_ENOUGH_MEMORY = 0x8). This is a seemingly undocumented flag. See the bottom of the MSDN page http://msdn.microsoft.com/en-us/library/windows/desktop/ms682489(v=vs.85).aspx
