Tibor Digana commented on SUREFIRE-1157:
----------------------------------------
File IO was also my idea and I still think it should work on all platforms.
Iterating over the lines should work well and then stream it back to the main
process in std out.
The forked process can be reused by default which mean that the file would have
to be reset every time a new testset comes.

> I believe this is caused by the native LevelDB library writing to stdout and
> breaking the communication between {{ForkingRunListener}} and {{ForkClient}}.
> It would be better if the communication between the main process and the fork
> happened over a socket.
