Explain the problem

I'm using parallel-webpack and webpack-bundle-analyser and it seems that parallel-webpack is causing webpack-bundle-analyser stop creating the reports midway so I sometimes end up with the correctly made stats or sometimes empty or invalid json files.
Might be related to: webpack-contrib/webpack-bundle-analyzer#152 (comment)

Expected Behaviour

to let webpack-bundle-analyser finish creating the report

Actual Behaviour

stops webpack-bundle-analyser from creating the reports causing indeterministic behavior

Steps to reproduce

has to be done on a large codebase with about 10 or more builds in parallel.
