CVS head now has the following LWLock probes, and more can easily be 
added. These probes can be enabled using the sample DTrace scripts at 
http://pgfoundry.org/projects/dtrace/

lwlock-acquire
lwlock-release
lwlock-startwait
lwlock-endwait
lwlock-condacquire
lwlock-condacquire-fail

If anyone wants to have access to a Solaris machine to play with DTrace, 
let me know.
