Fuzz Introspector is failed when building reports for Tarantool
and other projects, see [1]:
During handling of the above exception, another exception occurred:
File "/usr/local/lib/python3.10/multiprocessing/managers.py", line 817, in _callmethod
conn.send((self._id, methodname, args, kwds))
File "/fuzz-introspector/src/fuzz_introspector/datatypes/fuzzer_profile.py", line 359, in accummulate_profile
return_dict[uniq_id] = self
AttributeError: 'ForkAwareLocal' object has no attribute 'connection'
The issue (theoretically) is related to processing data in
parallel mode and cannot be reproduced locally. The patch
introduce an option for controlling parallel mode -
FUZZ_INTROSPECTOR_PARALLEL. When envronment variable is set to
`false` Fuzz Introspector will process data in sequential mode.
