Ah, okay, I didn't realize that.  When you said "we know there's none
anyway", I thought you meant "no subprocesses that use Guile", but I
guess you meant "no subprocesses at all".

I guess guix-daemon is the only one with subprocesses, and by the time
that's written in Guile hopefully Guile will have a command-line option
to augment %load-compiled-path.

In that case, I withdraw my proposal.  I'll make a new patch.

Sounds good.
