Does no platform understand that os is supposed to wrap this stuff for
you? Sigh. It seems like this same thing comes up in IronPython as
well. Oh hey, what do you know: "(The similarity of the two approaches
is not surprising considering that Jim Hugunin is the author of both.)"
Grargh.

I've patched TileCache to do this, though I implemented it in a
slightly different way. I'm going to try adn get IronPython up and
running and patch TileCache for that too, and then fix the threshold
bug, and release a final cut of the 1.x branch as 1.9 sometime next
week, after which I'll go ahead and start refactoring for 2.0 in a
branch.
