Yeah, I think Jason's idea is a good compromise.
But how do you think about adding G2LOCK_DECL macro
to declare the temp variable instead of pass it via an arg?

Well, my example is not so good (since I'm not a good programmer :-)
More particular case I know is:

{
 G2LOCK();
 :
 if (xxx) {
  G2_UNLOCK();
  return;
 }
 :
 G2_UNLOCK;
}

etc.

I this case, maybe the portmaster's mind has priority.. :-)
