My guess is that there are different methods due in part to
whether the API was written to be wrapped by g-wrap.  In g-wrap
we had a wrapper around Timespec so that you could use it
directly (instead of as a pointer), which required APIs to
pass in/out by value, not reference.   But yes, it should be
done consistently.   Does it matter to you which way?

Other than changing all the APIs everywhere, I don't see any reason
not to migrate, but I'd only migrate as necessary.  Keep in mind that
the Scheme API is derived from the C API so you'd have to go through
all the scheme every time you change a C API to make sure that it
doesn't break anything.
