One idea would be to add new arguments to LWLockAcquire as you suggest, 
but instead of modifying all call sites, decorate it with a macro that 
passes __FILE__ and __LINE__ as the extra arguments. The good thing 
about that is that it's a relatively small patch and you can easily 
switch it on/off with a #ifdef. And there's no need to push for 
inclusion of that into CVS, because it would be an easy patch to 
maintain yourself.
