ZFS vs torrents (transmission-bt)

 I've noticed, than when transmission downloads multi-file torrent to
ZFS, some files are not shown in "ls" output till they are closed
(completed). But not always! Some incomplete files are shown.

 I have "preallocation" option turned on and partially-downloaded
files are named with ".part" extension and renamed to true name after
completion.

 Some such files were lost when transmission-daemon was killed by OOM.

 I've never seen such behavior before, when my NAS was configured with
UFS2.

 What it could be?!
