OK. I'll switch to Solaris. Or do you something I don't about dtrace on
linux?
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.
