Ugh, do PHP often make breaking changes this close to release!?

But, yeah, looks good, thanks.

Btw you may or may not have noticed that the Unit project status
recently switched to "Unsupported". However I do intend to review and
merge such changes as this in my spare time, just don't expect a new
release any time soon...
