choose :: [a] -> TransientIO a

slurp a list of values and process them in parallel . To limit the number of processing threads, use threads

choose' :: [a] -> TransientIO a

alternative definition with more parallelism

collect :: Int -> TransientIO a -> TransientIO [a]

execute a process and get the first n solutions. if the process end without finding the number of solutions requested, it return the fond ones if he find the number of solutions requested, it kill the threads of the process and return It works monitoring the solutions found and the number of active threads. If the first parameter is 0, collect will return all the results

group :: Int -> TransientIO a -> TransientIO [a]

group the output of a possible multithreaded process in groups of n elements.
