- nsf.c: * change mem-count statistics from per-interp to per-thread * generalized GetObjectFromCmdTable() to ReverseLookupCmdFromCmdTable() * changed GetObjectScreenedByCmdName() to GetHiddenObjectFromCmd() * modularized interp.test to locate potential problems faster * partly simplified interp.test syntactically * deacivated a few tests in interp.test for the time being (runs commands after finalize)
