[Xorp-hackers] xorp_static_routes easy to crash.

[Li Zhao]

In many test cases, I found xorp_static_routes is very easy to crash. It is
very timer sensitive. This is a big problem in real time embedded system.
Here I attached stack trace:

#0 TimerNode()
#1 XrlRouter::get_sender at xrl_router.cc::423
#2 XrlRouter::send_resolved
#3 XrlRouter::send
