Apart from some local copies of xnu I have lying around I get this:
/Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/net/kpi_interface.h
/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/net/kpi_interface.h
/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/net/kpi_interface.h
/Users/laz/Documents/Apple/xnu-1228.5.18/bsd/net/kpi_interface.h
/Users/laz/Documents/Apple/xnu-792.25.20/bsd/net/kpi_interface.h

I just ran open <FILE> on all the files listed in locate, and they all
opened instantly.
Following Mike's advice, another interesting thing is that if I
disconnect from the network, I dont see the problem! In this
situation, fs_usage gives me:
lstat net/kpi_interfacefilter.h 0.003654 W Xcode
