All Clone Objects need to be protected from multithreading

[gordonwatts]

The following lines buried in the ROOT infrastructure:

   //create a buffer where the object will be streamed
   //We are forced to go via the I/O package (ie TBufferFile).
   //Invoking TBufferFile via CINT will automatically load the I/O library
   TBuffer *buffer = (TBuffer*)gROOT->ProcessLine("new TBufferFile(TBuffer::kWrite,10000);");

mean that any call to TObject::Clone must be protected via our generic ROOT lock.

And looks like the same crash is back:
