Machine: 4D/70g with SCSI cartridge tape drive
Problem: Tar times out too quickly while waiting for tape drive to rewind
Repeat by: Write enough data on the tape so that it takes ~45 seconds to
rewind, then issue the command:
tar c data; tar t
As soon as the first tar command finishes, the tape begins
rewinding, and the second tar starts running. The second tar
has to wait for the tape to finish rewinding, but it seems to
give up after ~30 seconds with the message:
tar: cannot open /dev/tape
