Doesn't look like its supported:
grep ADVISE rrd_config.h
/* #undef HAVE_DECL_MADVISE */
/* #undef HAVE_MADVISE */

Any other ideas?

Ignoring the mmap issue for a second, why would rrd ( I'm assuming its
rrd here ) require 831745 calls to write to the file for this single update,
surely this cant be good?
