I still think – though haven't actually tested it – that all those tmp  
file accesses are caused by bash's here-doc syntax to provide input  
for setkey. (The temp files are all named sh-thd-#UNIX_TIMESTAMP#)

Just like the example script in ipsec-tools, /etc/racoon/scripts/ 
p1_up_down does it:

setkey -c << EOT
spdadd ${INTERNAL_ADDR4}/32[any][any] any -P out ipsec
spdadd[any] ${INTERNAL_ADDR4}[any] any -P in ipsec

The only other alternative seems to be to put the rules into a  
dynamically created temp file, which I could then place anywhere, then  
use setkey -f to load it from there.

"setkey takes a series of operations from standard input (if invoked  
with -c) or the file named filename (if invoked with -f filename)."
