I went ahead and did this in branch jepler/test-nml-over-tcp. It is
based on master branch.
It passes on a 32-bit Ubuntu Lucid machine and fails on a 64-bit Debian
Wheezy machine.
For me, the specific failure messages on 64-bit are:
libnml/buffer/recvn.c 131: Recv timed out.
libnml/buffer/recvn.c 137: recvn(fd=4, vptr=0x18a904c, int n=40, int
