I would move this if above the previous if for a more consistent throwing experience.

throw new Error('callback is not a function');

You should use assert.throws() here.

process.nextTick();
} catch (e) {
// should handle this error at try...catch
if (!e) {
assert.fail();
}
}

process.on('uncaughtException', function() {
if (!exceptionHandled) {
exceptionHandled = true;
