Sorry, the problem you're trying to solve is just too ridiculous.
Threads might be the heaviest resource here, but no matter what you do,
having hundreds of objects active at the same time (bring back geocity
websites from the 90ies?) will cause a memory and CPU resource usage
problem. So what if it fails on Windows XP.

Maybe you're trying to argue from some sort of theoretical point of
view, but I'm thinking about practical issues, such as managing a
global thread pool. Regardless of "parallisation", for the problem at
this is also an overcomplicated and inefficient solution. Plus I didn't
even completely reject the idea of having some sort of thread pool.
