Well, sure, but if this libslirp is going to evolve into a
QEMU-independent library, such timer and save/restore hacks likely
should go away from the library and implemented on the side of the
consuming application instead.

FWIW, I know that WinUAE is using QEMU's slirp code, too.

I've got a question: Is there already a project page and public
repository for libslirp available somewhere? I did not find anything
useful with Google yet...
