I'm not aware of a way to reconnect with stderr, stdin, and stdout but I know that those file descriptors still exist in /proc/${PID}/fd.

Normally, in order to accomplish what you want, I would use app-misc/screen.  Screen is a very nice solution because you can reattach to an interactive terminal whenever you want.

Alternatively, you can redirect the emerge output to a log file:

emerge foo > /var/log/emerge-foo.log 2>&1 &
