In case anyone wants to know where to look to try and help improve the
throughput (yeah I know it's very early on but the code is still quite clean
and the opportunities only get rarer from here on in) here's a bprof output
of the profile log. The net_srv was run for 100 rx datagrams, mostly pings
from another machine.
