Good to know :)

This appears to be an issue with using /tmp as the target dir, using another
directory and I can run the import without issue it seems. Other tests also
hang with the same issue:-
zpool_upgrade_002_pos
zpool_upgrade_003_pos
zpool_upgrade_007_pos
zpool_upgrade_008_pos
zpool_upgrade_009_neg

Would it be an issue to change the directory?

This is related to the following PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=161968

Doesn't seem to effect current or stable/9 I've only managed to reproduce
on only stable/8, so already getting benefit from this excellent work :)

Whats the best way to disable a specific test Alan?

Thanks Alan, good to know.

Just completed
