-
- The first option is good for enabling the second option; SunOS 4.x only uses
- kernel LWPs to support asynch I/O.
-
- The second option is good for Sybase, which uses async I/O on raw
- partitions, and may be useful for other applications such as databases
- or tape dump/restore that use async I/O on raw disks or tapes.
