The same way that you implement different traps for different portions
of a shell script that does not use functions. You can use 'trap -p' to
save off the previous trap definition, install your new trap, then when
done with your code, call trap to set things back to the value you saved
off earlier.
Or, by creating a subshell within the body of your function, and
changing the traps local to that subshell.
