Thanks all of you for your input...
i was suspecting that i would get replies like these...they all
basically come down to the same conclusion, that the functional style
favours the STM abstraction and avoids some of its inherent bottlenecks...
just one more thing though...
what i omitted to mention before is that the speaker said that the
comparisons involve C++ and Haskell implementations of the same STM(s).
and so when i asked him:
"isn't it easier and simpler to deal with immutable data-structures ?"
he replied that his work is essentially a quest for performance in STMs
and thus starting with immutable collections would not be a clever move...
i was trying to ask "why does the queue need to know so much (when to
block/release)? isn't that the root of the problem?" and what i got back
is essentially:
"well... it's impossible otherwise!"
Is the situation really that bad? It can't be, can it?
Jim
