Morten, if you had some runnable code that demonstrated the behavior, we
would all have a much more precise description of what's happening.  :-)
And a description of the networking environment, e.g. 10GBit local
Ethernet vs. 9.6Kbps/sec to lunar orbit.  (Running in virtual machine
environments (Xen, VMware, ...) can also play tricky games.)

If I recall correctly ... the net_kernel doesn't rely solely on the tick
messages between nodes: any message from node A -> B should reset B's
tick timeout counter.
