multiprocessing problem.

[jerzyorlowskimim]

I try to run pileline using mutliprocessing with hyperscan.

i use with closing(Pool(args.nr_proc)) as pool: to define process_pool
I use pool.apply_async() to generate list of testks

When I run tasks I get:

    raise self._value
  File "/usr/lib/python3.9/multiprocessing/pool.py", line 537, in _handle_tasks
    put(task)
  File "/usr/lib/python3.9/multiprocessing/connection.py", line 211, in send
    self._send_bytes(_ForkingPickler.dumps(obj))
  File "/usr/lib/python3.9/multiprocessing/reduction.py", line 51, in dumps
    cls(buf, protocol).dump(obj)
TypeError: cannot pickle 'hyperscan.Database' object```
