In connection with nodejs/node#712 (comment) I've found that wrapping this method solves a timing bug that appears to be deep in the bowels of node (or perhaps it is somewhere in oauth2, but seeing that it comes from C code, I don't think that's the case).
I can faithfully reproduce the bug, but haven't been able to isolate it outside of passport / oauth2 (probably due to the nature of the timing and the number of callbacks).
node v0.10.35 does not manifest the error.
