Carrie, actually, all vegetable oils will go rancid with exposure to air and 
heat over time.  The only difference is how resistant each is.  Some oils 
are much more stable (olive, macadamia, coconut) and some are volatile 
(flax, canola, soy).  Volatile oils are missing hydrogen bonds and they are 
subject  to break down much more quickly.  They produce a carcinogenic smoke 
when used in frying.  Many Chinese women suffer lung cancer because they 
stir-fry with soy oil.

Use on a floor may be no problem except that what we ingest what we breathe 
(molecules).  Is that necessarily a problem?  Beats me, but I don't have 
warm, squishy, "I can't wait to oil my floor" feelings about it. Where the 
drying process probably reduces the outgassing effect, I see that 
re-applications of the oil (and maybe the turpentine) are advised, which 
might be counter productive for health or mildew.
