> Unix file open supports a number of options, e.g. O_DIRECT O_NOATIME etc.
> Currently open_write takes one option "overwrite", but there are several other options
> which would be nice, including CLOSE_COMPLETE (finalize the object when nbytes == ndone
> and expect a close, preventing the head from being split from the data in cases where
> the object is small) and SYNC which would call COMPLETE when the object has hit
> the disk and would be recovered in the case of a crash.
