That was written nearly 8 years ago, in response to growing pains in our former 
all-DLT environment.  Our weekend Full back then was larger than 15 tapes 
(eventually becoming 24+), and it was imperative to speed that up by doing as 
few parallelism-based operations as possible (based on early discussions here 
on this list).  I had plans to split operations to allow four of my eight 
drives to spin, but with disk as my primary target, and our switch to LTO, 
that's kinda moot now.

One caveat here - recovering from something happening in the middle of this 
setup can be utter hell.  Plan for it...
