Glad to hear that.

Hmm, good point. I was also wondering why such a massive number of
route entries remained despite the periodical cleanup mechanism. Then
I found another bug, which set the cleanup interval to a huge value
(almost infinite in a practical sense).
The patch below, including the previous fix, should also solve the
problem (I must confess I even did not compile it, so please be
careful). Perhaps you can then live with the original rtexpire value.
