    AFAIK, the only needs for implementing 'renice' are the functions
'setpriority()' and 'getpriority()' (the last is only needed to
validate some parameters).

    You should, and you should send me to it XD

    Don't worry, I know it is a very hard job. I didn't pretend to
bother you ;)

    I may be wrong, but any system capable of running 'nice' should
be capable of running 'renice'. Both use 'setpriority()', don't they?

    I don't have access to many systems, unfortunately, but if you
want me to, I can google a bit to see manpages for different systems.

    Implementing 'renice' under Linux is pretty trivial, but doing it
portably is another issue :(. I'll try to investigate about current
practice under different systems and if I end up with any interesting
idea I'll let you know.

    Thanks a lot for your support, for coreutils and for taking into
account my suggestions; I'll try my best to help you in any way I can.
