Time being of the essence, here is the patch I posted last year, this

"fsync" (default) or "syncfs" if you have it.
Cfbot told me to add HAVE_SYNCFS to Solution.pm, and I fixed a couple of typos.
Thanks for the patch!

Isn't this a bit misleading? This may cause users to misunderstand that
such fsync can happen only in the case of crash recovery.
