Re: PROPOSAL: Control over process cleanup in `save-buffers-kill-emacs'.

Given your use case, it seems a lot less hackish to just introduce a 
user option that is one of

1. an abnormal hook called with each new process started

This would allow the use of `set-process-query-on-exit-flag' in a 
natural way, but would run before any existing code configured the 
process in similar fashion.

2. a new normal hook called at the beginning of `save-buffers-kill-emacs'

This would also allow the existing flag to be used, and would be 
unsurprising and easy to find.

3. a regular expression matching process and/or process-buffer names for 
which not to query on exit

This would allow access by non-programmers, but would make the query 
flag something of a lie.
