Hello Maxime,

Thanks for your review.  I took your comments into account and actually
wrote some more patches to clean up start_child of potential thread
unsafe practices.  Since these are not guix-specific, I sent the whole
patchset to guile-devel instead [1].

How would you suggest we do that?  Since these are mostly racing issues
between threads, I don't know how we could reproduce these reliably in
tests.
