Based off of this comment:

This seems like it might be a separate issue. Should we mandate that drivers that can SHOULD set the FD_CLOEXEC or (when available) the SOCK_CLOEXEC flag on sockets?

Also, this spec doesn't seem to say anything about how the connections should be created at a low level. Setting flags like TCP_NODELAY. Should it?

There are some details of how connections in drivers function, such as TCP flags and forking behavior, that might benefit from standardization.
