问题
I use iTerm2 (Build 1.0.0.20130319) and Vim (bin of MacVim Snapshot 66) on top of OS X 10.7.5 as my CLI editing team.
In iTerm2 I defined to use a non-blinking vertical bar as a cursor shape. In Vim I defined
" Enter insert mode (Cursor shape: vertical bar)
let &t_SI = "\<Esc>]50;CursorShape=1\x7"
" Leave insert mode (Cursor shape: block)
let &t_EI = "\<Esc>]50;CursorShape=0\x7"
to be able to distinct between insert and normal mode. Basically this works fine. The problem arises when I leave Vim and return to the CLI. What happens is that the cursor does not return in its initial shape (vertical bar). Instead it decides to stay in a block shape.
Could I reset the cursor to it's initial shape or force it to return to be a vertical bar? I Could imagine to trigger an event on e.g. "VimLeave". But I don't know what I could pass as an escape sequence.

After a little bit more digging into :help I found out that
autocmd VimLeave * let &t_me="\<Esc>]50;CursorShape=1\x7"
would revert the cursor shape to its initial, or let's say a defined, shape. That works great so far.
Does anyone know downsides of that approach? Besides VimLeave one could also trigger VimLeavePre or QuitPre.
EDIT: Even better there's a new plugin available which does exactly what some people are looking for.

It's a little bit configurable, too:
let g:togglecursor_default = "block"
let g:togglecursor_insert = "line"
let g:togglecursor_leave = "line"
let g:togglecursor_disable_tmux = 0

Did you try this?
autocmd VimLeave * let &t_SI = "\<Esc>]50;CursorShape=1\x7"

I tried this method before because I was used to Gvim's cursor style when switching to terminal. But I met the same problem and had no way to fix it.
Finally I have been using changing Cursor colour method. Once I got used to the style, I'm quite happy it and forget the cursor shape at all.
Change Cursor colour method
autocmd InsertEnter * set cul
autocmd InsertLeave * set nocul
Then set similar but different colour for Cursor than Normal in the theme if there is no built-in scheme in this theme.

I'm using Iterm with regular vim. This sets cursor solid on launch vim, blinks on insert mode. And returns to blinking on exit vim.
augroup myCmds
au!
autocmd VimEnter * silent !echo -ne "\e[2 q"
autocmd VimLeave * silent !echo -ne "\e[1 q"
augroup END
