To be correct, such a program must be able to deal with this failure
and fall back to a smaller socket buffer size. There is no portable
way to distinguish hitting the relevant limit in this case from a system
which really is out of network buffer space.
Also, setting this limit by hand disables automatic socket buffer sizing
for TCP sockets, which is a thing worth keeping in mind.
