As promissed in my last post, I opened the issue #367 at google code to fix the problem reported.
My first patch wasn't accepted, but I though that it would take this way, since the patch was very punk (it would introduce undesired backward incompability). The second patch was better, but I was not happy with it... it just relied on environment variables, what is a crappy thing.
The final fix by Mr. Holkner implemented lazy loading support... IMHO his implementation was not good, but the idea is very cool. The guys there seemed not so friendly, so I leave this detail apart.
By the way, I'm happy to have helped with something in this project.
