Yeah, a few operating systems do that for various tape operations.
Chg-zd-mtx handles it for loads by polling the device until it's
ready, but should probably be patched to handle the same for ejects.
We're going to rewrite this script in Perl eventually, and add the
capability to specify properties to control its operation (rewoffl vs.
eject, returns early for which operations, etc.).

In the interim, inserting sleeps is a good solution.
