Note that flight rate is completely dominated by flight costs, including
the cost of ground ops and amortized development costs, and that the
costs of development and ground ops are completely dominated by the
design. Unfortunate choices of technology and design are precisely why
the Space Shuttle is such a failure.
By flight rate, Monte meant how many flights you could consistently
get
over a given period of time. Not "rate" as in "price". That said, I
do agree
with your point--the engineering and economics are intertwined.

This should be sufficiently close to the paradigm of "dispose straight away and let threads do their thing" that even the person for whom "that's just the way he thinks" could easily comprehend and use such a design.... However, your proposed design can be implemented in a couple of ways: a single try/catch at the very top of the thread's call chain, or a try/catch around each and every possible use of a disposable object....
