Thanks Eric, the new module works like a charm. Here's the installation
I did:

root at omnios:~# beadm create -e omnios-r151008 omnios-r151008-fix
Created successfully
root at omnios:~# beadm mount omnios-r151008-fix
Mounted successfully on: '/tmp/tmp.JAaqdb'
root at omnios:~# cd /tmp/tmp.JAaqdb/
root at omnios:/tmp/tmp.JAaqdb# cp
~/zfs-driver-with-txg_wait-fix.amd64.r151008 kernel/fs/amd64/zfs
root at omnios:/tmp/tmp.JAaqdb# cd
root at omnios:~# bootadm update-archive -R /tmp/tmp.JAaqdb
Creating boot_archive for /tmp/tmp.JAaqdb
updating /tmp/tmp.JAaqdb/platform/i86pc/boot_archive
updating /tmp/tmp.JAaqdb/platform/i86pc/amd64/boot_archive
root at omnios:~# beadm umount omnios-r151008-fix
Unmounted successfully
root at omnios:~# reboot -p

And here's the test:

dd if=/dev/urandom of=test bs=1M count=128 ; sync

On the original BE this hangs, on the new BE works without a hitch.

I'd say ship it!

Best wishes,
