3/4 is an awful lot. That would be 15 GB on my system, which explains
why the "5 seconds to write" rule is dominant.
3/4 is 1/8 * 6, where 6 is worst-case inflation factor (for raid-z2 is 9
actually, and considering ganged 1k block on raid-z2 in the really bad
case it should be even bigger than that). DSL does inflate write sizes
too, so inflated write sizes are compared against inflated limit, so it
should be fine.
