Overhead? Did you run any benchmarks to prove it?
I find list-version much more elegant that using an array.

I also don't like the idea of calling handler method with two locks
held (one sx and one mutex)...

There is still an unresolved problem (in your and our patch as well) of
using ifnet structure fields without synchronization, as we don't have
access tointerface's internal mutex, which protects those fields.
