Now with current Guile I get the following:

scheme@(guile-user)> (compile-file "/tmp/prog_to_spec_TEST.scx")
$2 = "/home/wingo/.cache/guile/ccache/1.9-0.A-LE-4/tmp/prog_to_spec_TEST.scx.go"
scheme@(guile-user)> ,t (load-compiled $2)
clock utime stime cutime cstime gctime
23.21 22.90  0.00   0.00   0.00   0.28

23 seconds.

This is still the case.
