Thanks a lot for explanation of implementation internals!
It seems like to make majority of console applications happy and avoid
their code modifications, we might want to add solaris support to gpm or
moused package.
Is somebody on the list willing to hack on it? I will be happy to try to
push a proposed solution to the next release of NexentaOS.
