ztest should print out zfs debug buffer before exiting
zfs - Zettabyte File System
Analysis by George Wilson:
ZFS maintains an internal debug buffer that is very similar to the on-disk history for the pool. It would be useful to have 'ztest' print out the contents of that buffer just prior to it exiting. This would aid in debugging some of the complex problems that 'ztest' seems so good at finding.
