Many operating systems are not smart about managing this and allow large amounts of dirty data to accumulate before deciding to flush it all at once, causing long delays for new I/O requests until the flushing finishes. This change attempts to alleviate this problem by explicitly requesting data flushes after a configurable interval. On Linux, sync_file_range() is used for this purpose, and the feature is on by default on Linux because that function has few downsides. This flushing capability is also available on other platforms if they have msync() or posix_fadvise(), but those interfaces have some undesirable side-effects so the feature is disabled by default on non-Linux platforms.
