So that other people not have to make the same mistake as me and mistake
SIOCINQ and FIONREAD, I have patched an update to
Documentation/networking/dccp.tx (next email).

Have you got the sources available for the DCCP plugin: it would be 
interesting to see how it is used. After the handshake ioctl(FIONREAD)
returns 0 for a while, and same after last read.

If done intelligently, this could solve the End-of-File problem reported 
earlier by Remi Denis-Courmont.
