file handle leak to child processes

[uli42]

The nxdialog process inherits all the file handles of the nxagent (see /proc/.../fds), e.g. the one of the stats and error files. This is not a real problem but as nxdialog does not require them this should be improved.

OTH this could be used for communicating back more information from nxdialog to nxagent.
