Bash's feature of being editable while it's running is particularly concerning 
for environments where there are many developers or where tools like rsync 
might be used on a source directory.

See below for an example/solution:


I'd like to add a very simple command line flag to bash that forces it to make 
a temporary copy of the script that's running so that developers of scripts in 
these environments can continue to use tools like rsync or git, etc. to do code 
releases, but don't have to worry that running scripts will have unpredictable 

Is this something that the current maintainers would be interested in including 
in the main code?
