This is a really interesting workaround!

Yes, ipfw is vnet-capable since a long time and it works as good
as the non-virtualized version. Well... except for dummynet which
isn't virtualized yet.

My point is, VIMAGE is really stable except for:
1) tearing-down a vnet
2) running non-vnet-ready code (pf, dummynet, lagg, ipf etc)

Number one is trigged by destroying a jail.
Number two is usually triggered *immediately* after trying to use a
non-vnet-ready driver.

You can avoid these two and if you avoid them it is perfectly stable...

Also, I have to say that i like vimage very much so i might be biased:)

Just my 2 cents,

Nikos
