Finder in OS X 10.8.2 (Build 12C60).
GoFlex Desk (0x50a5) connected to
Sitecom USB 2.0 Dock CN-022 (0x0022); that hub connected to a
MacBookPro5,2 with 8 GB memory.
Following a send and receive with intentionally little free space at the destination:
25.08 GB available according to the status bar of Finder,
35.3Gi free according to zpool,
6.21Gi free according to zfs.
By exporting, disconnecting then reconnecting I get Finder to report
6.67 GB available, but I remain puzzled by differences between figures at the command line.
35.3 - 6.21
= 29.09
So, what's that 29.09 Gi?
Any guesses? (If I'm overlooking something basic, sorry.)

Sorry, I found a probable answer:
ZFS FAQ (Community Group zfs.faq) - XWiki: Why doesn't the space that is reported by the zpool list command and the zfs list command match?
Time for me to do some reading … keyword overhead.
