In the case of the < or > forms, the shell runs process LIST asynchronously. If the system supports the /dev/fd mechanism, the command argument is the name of the device file corresponding to a file descriptor; otherwise, if the system supports named pipes (FIFOs), the command argument will be a named pipe. So evidently your system does not support /dev/fd, and zsh is having some trouble managing the named pipe. What version of zsh? What happens if you try echo <(sleep 2; date) ?? I can't reproduce your error, but all the systems to which I have access are systems that support /dev/fd.
