This is a known loose end. I would like to add code to fsync the rev
and prop files before returning from the commit, but APR does not have
an interface to fsync(), nor could I find a Unix-specific interface to
get the fd so that I could put a call to fsync() inside #ifndef WIN32.
I haven't thought of a way to circumvent this problem yet, but hopefully
there's an option.
