On OS X 10.9 with PHP 5.4.10, this function seems to correctly return bool(true) or bool(false) and not anymore integers.

Exceptions regarding existing active transactions were thrown while I was almost certain sufficient checks were in place.
However, I quickly found out that a strict boolean comparison to PDO::inTransaction() was failing.
Using var_dump I learned that this function was returning integers, not boolean values.
var_dump(PDO::inTransaction()); // int(1) || int(0)

This method actually seems to work fine on PHP5.3.5 (and probably a few older versions).
