This should also work fine with SCTP, too. Using the sctplib/socketapi
implementation, this will work (see the rsplib RSerPool package for example
code: http://tdrwww.iem.uni-due.de/dreibholz/rserpool/). If you are using
Solaris kernel SCTP, this seems to be a bug and you should write to the
Solaris mailing list.
