My understanding is that "boiled linseed oil" isn't actually boiled.
It has various chemicals (usually nasty and lead based) added to it to
make it dry quicker.  Buildingforhealth.com sells some linseed oil
that has some less-nasty things added to it to make it dry quicker; I
bought some for a floor I finished last month, and it worked great.
It's made by bioshield.  A little pricey though, but with kids playing
on this floor (and likely babies licking it at some point) I didn't
want lead in the top layer :)
