I run RELENG_7 on my home machine, using ZFS with a zpool of two disks
(basically the equiv. of a RAID 0 array). The storage pool is about
1TB, and mainly contains ISO images. The network interface on the boxes
are gigE, and I copy data quite regularly. I have absolutely no ZFS-
related tuning parameters set in my loader.conf or sysctl; I'm using
all the stock out-of-the-box settings.
I run Samba as well, which has shares for numerous directories on that
I haven't run into any problems that appear to be ZFS or Samba-related.

I have seen something similar happen, and I believe it to be a Windows
"problem" (if you can call it that) more so than a SMB/CIFS or ZFS
Say you have /foo/bar as a shared SMB resource via Samba on a UNIX box.
If on the Windows machine you browse to that folder (in Windows
Explorer), then on the UNIX box rm -fr /foo/bar/someotherdir, you will
not see the someotherdir directory disappear in Explorer until you
actually click Refresh.
Otherwise, I haven't ever seen what you've reported. I'm not sure why
you think it's related to ZFS though; the behaviour you describe should
happen on any underlying filesystem or LVM equivalent.
