rump tcp/ip stack:
* sshd likes to fork and then re-exec itself
==> trap execve() and augment the env with the current parameters
essential to a rump kernel (kernel communication fd, information
about dup2'd file descriptors)
* sshd likes to play lots of games with pipes, socketpairs and dup{,2}()
==> make sure we do not close essential rump client descriptors:
dup() them to a safe place, except for F_CLOSEM where we
simply leave them alone. also, partially solved by the above,
make sure the process's set of rump kernel descriptors persists
over exec()
* sshd likes to chdir() before exec
==> for unix-style rump_sp(7) sockets save the full path on the
initial exec and use it afterwards. thread the path through
the environment in execve()
