This has been mentioned before but there are embedded use cases where the requirement is to have a low overhead OS using 32 bit libs and binaries to save memory but the main application (like a database server) runs in 64 bit mode with 64 bit libraries so it can take advantage of system memory, extra instructions or so forth. This applies to mips and powerpc as well as x86. The implementation is fairly self contained so if you don't want multilib, you shouldn't even be aware its there... Cheers, Richard
