You have brought up a good point - batch jobs should be able to read 
from disk and write to disk even though we want to disallow tapes.
TVs, DOCRT > 0will not be allowed.  What I am still trying to figure out 
is whether your jobs really are not starting in 15sec or what is going 
on.  The prtmsg of the full session should show these breaks if they 
occur.  Nothing in the task start-up has changed in a long time - unless 
perhaps you compiled locally for 31DEC07 and are using binary for 
31DEC08.  I cannot think of anything in your local setup that should 
result in different behavior for 31DEC07 and 31DEC08 also.  I hesitate 
to raise this timeout for everyone without some greater understanding.
I will look at the "tape" tasks issue.
