KNOWN ISSUES
Task attributes is incomplete (all tasks are treated as if they have
the SIMPLE attribute.)
SCSI task management is incomplete.
NOP-In is incomplete.
The target never sends a NOP-In of its own accord.
Header and Data Digest in a discovery session are not implemented.
Out-of-memory situation leads to the system crash (There are still some
out-of-memory bugs.)
