This probably means we'll have to write into a buffer in each submodule and write them out in one step. I wonder if that's enough, AFAICT we could still get race conditions when two threads write their buffers at the same time. I wonder if Gradle already provides a mechanism for that kind of problem.

[jochenberger]

Could you please try whether b3925f6 fixes the problem?

[jochenberger]

I believe this is fixed now, feel free to comment if the problem persists after 0.5 (which is not yet released).
