The hardest part was fixing two mutual recursive imports; somehow changing "import foo" into "from . import foo" where foo and bar import each other AND both are imported from init.py caused things to break. Bah. Hm, this is possibly a flaw in the explicit relative import mechanism.

Actually, this sounds rather like a problem that happens in Python 2.4 as well.

If you have a package 'foo' containing modules 'bar' and 'baz', and foo/init.py imports both bar and baz, then 'import foo.bar' will fail inside of baz. You have to use 'from foo import bar' or it doesn't work. We run into this a lot in Chandler, which tries to expose package APIs from the package init modules.
