[datatable-help] fread warning

[eddi]

I'm getting this warning from fread:

"Mapped file ok but madvise failed"

It seems to be purely a function of file (and, looking at the code, I assume
memory page) size and is system dependent, so I can't really give you a
reproducible example. Adding or removing a single character anywhere in the
file results in the warning disappearing.

Two questions - should I care about this warning? And can the code be
changed to be aware of this edge case?
