    udvm: free the buffer *before* throwing the exception

    Freeing it after the exception doesn't do much, for obvious reasons. Also
move
    the allocation a bit later, and add modelines.

    This fixes one major memory leak, although on inspection this code still
isn't
    safe since there are exception-throwing functions called all over the place
with
    glib memory active. Outside the scope of this fix though.
