Why is this virtual? Also, it needs a comment.

Done.

[Alexei Svitkine (slow), 2013/06/19 14:58:31]

How does this work on platforms other than Mac? The recursion doesn't happen
there, so is the test still valid in that case? Same question for the other
tests.

[noms (inactive), 2013/06/21 23:11:47]

Tests shouldn't work, so I've ifdef'ed them.
