For instance stripping .comment out of the binaries strikes me as a shot in the dark; I'm not sure whether mapping an extra 400k in memory is such a huge performance hit...
When you have 20-odd shared libraries linked in with every application, that 400k soon becomes 8Mb. Even if it was, all-up, 400k - what happens if that 400k of useless cruft then pushes the required memory over a page boundary? And the new required page due to memory pressure requires paging something else to disk?
You may call this nit-picking but there's a variety of applications where there is substantial memory pressure (think so-called embedded devices like mobile phones, pda's and network appliances) where 8Mb can be 25% (or more) of your RAM.
