What is the fastest way to detect modifications to any listed buffer?

I would like an indicator in my 'titlestring' that informs me if ANY changes are present in ANY listed buffer. This would be more like a global indicator for the 'modified' setting. What is the most efficient way to do this?

Currently, I've taken the naive approach:

function! g:ChangesExist()
let l:bufferList = filter(range(1, bufnr('$')), 'buflisted(v:val)')

for l:bufferNumber in l:bufferList

if getbufvar(l:bufferNumber, '&modified')
return 1
endif
endfor

return 0
endfunction


This seems like the most direct method, but I'm wondering if there's some simple option or function call that I'm missing...
