Seems I was wrong, and this issue is not yet fixed. Yesterday, before replying, I've tried to check the state of the bug, but b.o.o. always returned "We encountered an unexpected error. Please try back again." :-( I repeated my test case (creating a pcfs filesystem on a lofi device from an 80gbyte file on zfs), and the write times with a current opensolaris kernel have improved by a factor of 4 (~ 10 seconds instead of 40-50 seconds), but I guess part of the improvement is because of a hardware upgrade here (zpool on two s-ata drives, instead of one p-ata drive).
