Probably not that long, uranocene (a comparatively heavy molecule of similar structure) apparently has an appreciable vapor pressure of 10^-3 torr or so at 200C.
Weight does matter of course, but intermolecular bonding/affinity is generally the more important consideration.

Let's replace "forever" with "extremely slowly". > Weight does matter of course, but intermolecular bonding/affinity is generally the more important consideration. I agree, so I choose a non-polar material to compare. (i.e. petrol instead of water). Probably petrol and parafin are very saturated and linear, and both change the properties of the molecules a lot. I'd better have choose something with more double bounds, but I don't have a very good example at hand.
