You might find it more useful (at least I do) to try the check, say,
30 times and sleep for 20 seconds. Gives a maximum wait time of ten
minutes, but doesn't create new processes each second.

I believe you're confusing the parameters of the script with the ones
to this function alone.
In the distributed version, wait_for_drive() is called with only one
parameter, and that is the tape drive to check.

I guess this will break if you ever want to check anything else than
/dev/tape (which, for *my* kernel and mt, is the default to use when
not supplying a parameter). $4 will be empty in wait_for_drive...
