The STC fails with the 2013-05-24 32-bit snapshot and the 1.7.19-6
64-bit release. The full libapr1 test suite fails with the 64-bit
release if I include the testdso test cases, but succeeds if I exclude
them. For 32-bit, the full test suite passes even with the testdso test
cases. I don't understand why that is.

That is, my STC shows that a dlclose() will break subsequent fork()
calls, but that breakage doesn't occur with the full libapr1 test suite
on 32-bit for some unknown reason.

But as long as my STC isn't completely ridiculous, fixing it might fix
the 64-bit test suite.
