Activate the statement:

   SafeDelete(fInterpreter);
This sattement was disabled because of a crash in CINT destructors.
This problem seems to be fixed with teh new version of CINT.
The reason for activating it, is that cint opens files (like bool.h) that
it closes only when explicitly told (by scratch_all and G__close_inputfiles).
Currently neither is being called at  the end of a ROOT process so a few
files are left open
