There's no point to have shadow worklife shorter than the claim, right?
There is no point unless you are worried about the shadow leaking some
resource (memory? descriptors?) between jobs, or if you want to do
something exotic like set things up so you have a separate shadow log
file per job. FWIW, we are not aware of any such resource leak bugs in
the shadow ...
Are there any strange effects if shadow worklife is significantly longer than claim worklife?
None I am aware of... but be aware that as currently implemented,
shadows will only get reused for the same claim. So shadow worklife is
effectively bounded by claim worklife.
