[Help] programm execution leads to infinity background loop after... what reason?

[Eld0r]

changed my design from extending thread to just using 
taskPool.parallel.
seems like my implementation left to many open threads in 
background and forcing the operation system to cut them off.

thought start() and join() allowed me to use start() again on the 
same thread object in next loop.
But there is some leakage... are they not 'self-closig' after 
finnishing run() ?

works now
but you are welcome to leave a statement.
