As for the timeouts, check if your tuning (i.e. the migrated files
like /etc/system) don't enforce long TXG syncs (default was 30sec)
or something like that.

Find some DTrace scripts to see if ZIL is intensively used during
these user-profile writes, and if these writes are synchronous -
maybe an SSD/DDR logging device might be useful for this scenario?

Regarding the zfs-auto-snapshot, it is possible to install the old
scripted package from OpenSolaris onto Solaris 10 at least; I did
not have much experience with newer releases yet (timesliderd) so
can't help better.
