Oh my god - Overlooked that ;-) - funny that -  Its a bit tricky as it not possibly to dump a kernel
when the swap is on ZFS - I did a test with all debugging enabled and the problem
did not show up - which makes it somewhat nasty - I check if I can reproduce it 
with only DDB enabled 

But as I said - I have been running with root on ZFS for quite a while without problems - 
There are however two things that does not make much sense 

1) number of vnodes are reduces to 100,000  by the kernel (AMD64)
2) If I extent the cache size "wildly" it seems to be stable about 600MB +- 67MB
