I just read the following article:
http://madpenguin.org/cms/index.php/?m=show&opt=printable&id=6045

Near the end, this line caught my attention: "the delay means that
while a crash will not destroy FS, it might result in significant loss
of data that has not yet been written to the disc."

I'm just wondering if this delay parameter is tunable and what the default is.
