Well, posix says data should be kept. The solaris man page for madvise,
since it proposes a MADV_FREE case too do agree with posix.

I've tested the program (thanks Andy) on solaris 5.8, it does work fine.
On OSF1 it failed on the anonymous case.

Some people may want their data to be kept, so the safe side is to keep
data safe, i.e. both kernel and manpage be corrected, but leave a bug
notice in the manpage about previous kernels.

Samuel
