Not a good idea. Programs like cpio, tar and others that work with the
tape drive generally have a number of files open; not just the tape
drive. The tape device interrupt you think you are waiting for is a
release of all the file access control blocks in memory. Crashing tar or
cpio causes wholesale swapping to occur.
