Review comment:
'max_concurrency_value' is cooperating with the 'ParallelLauncher' which
is running the worker thread is a thread_local variable, so we need to make
max_concurrency_value to be a thread_local variable too, then when different
thread run 'ParallelLauncher', the different 'ParallelLauncher' can get
different value of 'max_concurrency_value'
