Most of the time, if you don't need a cloned route allocated, you can
just use rtalloc_ign(&ro, RTF_CLONING) to just get a reference to the
existing rtentry. Not allocating a new cloned route saves work and
time for the rtalloc code.

Maybe you do some nasty things to rt here?

rtalloc() and rtfree() are used quite often in the network code and
otherwise work fine. The odds are high that you are doing something
wrong.
