Tom wrote it, so he's the expert. Basically it allows multiple
systemtap probes to share a netlink channel. There are other possible
approaches, including changing the kernel headers to allow us a big
block of netlink channels. However, the transport module seems to work
well.
What don't you find convenient about it?
