Setting up a TCP/IP connection in non-blocking fashion is very different
from doing UDP. TCP/IP also comes with the possibility of getting partial
writes, especially under benchmarking conditions, which requires buffering
and keeping state.

For this reason, none of the UDP-based tools has "just enabled" TCP/IP, we
would've if it were straightforward.
