This is a nice change -- looks good to me. Would be nice to fix Travis failures, but it looks like the important cases are passing.

It looks like there are some new build failures in Travis. Wonder if these are related, since they are in the same file modified by this PR?

src/init_finalize.c:43:21: error: variable has incomplete type 'struct timespec'
    struct timespec napstruct = { .tv_sec  = 0,
                    ^
src/init_finalize.c:43:12: note: forward declaration of 'struct timespec'
    struct timespec napstruct = { .tv_sec  = 0,
           ^

Yeah, I need to fix a lot of Travis issues in my open-source projects. Just haven't had time.

@jdinan The struct timespec are stupid POSIX/BSD/ISO problems and I cannot reproduce locally. I will debug them in another branch.
