Nice idea. I've expanded it a bit by changing the
CursorHold to get rid of itself and restore the previous
value of 'updatetime'. The following was added to your tip:
" The following is a self destructive version of the
" CursorHold autocmd. It also restores 'updatetime'.
let s:Pecho=''
fu! s:Pecho(msg)
if &ut!=11|let s:hold_ut=&ut|let &ut=11|en
let s:Pecho=a:msg
aug Pecho
au CursorHold * if s:Pecho!=''|echo s:Pecho
\|let s:Pecho=''|let &ut=s:hold_ut|en
\|aug Pecho|exe 'au!'|aug END|aug! Pecho
aug END
endf
" Test of above
au! BufEnter foo call s:Pecho("Entered foo")
" Now even changing to "foo" in a different tab page
" will print the message.
I filed another change at http://www.vim.org/tips/tip.php?tip_id=1379
to this piece that makes it safe when two or more scripts use
this same technique simultaneously (otheriwse, &ut restoration
can go wrong, order of autocommands triggering is unpredictable).
Bill, do you think the "if s:Pecho!=''|' check in autocommand is necessary ?

let s:Pecho=''
fu! s:Pecho(msg)
let s:hold_ut=&ut | if &ut>1|let &ut=1|en
let s:Pecho=a:msg
aug Pecho
au CursorHold * if s:Pecho!=''|echo s:Pecho
\|let s:Pecho=''|if s:hold_ut > &ut |let &ut=s:hold_ut|en|en
\|aug Pecho|exe 'au!'|aug END|aug! Pecho
aug END
endf
In this form, I think it's safe for use in plugins.
