Perhaps I was unclear. They were run as:

address@hidden:~/src/guile/vm$ ./pre-inst-guile-env bash
address@hidden:~/src/guile/vm$ time for i in 0 1 2 3 4 5 6 7 8 9; do 
libguile/.libs/lt-guile -c 1; done

real    0m0.098s
user    0m0.059s
sys     0m0.026s

I don't think there's overhead here. There certainly is if you time
./pre-inst-guile instead:

address@hidden:~/src/guile/vm$ time for i in 0 1 2 3 4 5 6 7 8 9; do 
./pre-inst-guile -c 1; done

real    0m0.307s
user    0m0.164s
sys     0m0.120s
