The toString method will be doing string conversion and invalidating the
format... not sure why I felt that necessary. I've updated it to
> fs.appendFileSync('executionData/'+ this.logFileId +'.exec', data);
and the and merge now gets through some of the files before complaining.
The stack trace is:

I see old mentions of concurrency issues on google, but these files are written
synchronously in a single thread, so that should not be the issue here.
