> tika-eval uses tika-batch, but it only uses the child batch process because if there's a failure there, something went seriously wrong, and there shouldn't be a restart.
> The problem is that the child process uses stdin as a potential interrupt from the parent process.  If the child is run by itself, it uses the system's stdin, which can cause problems w nohup:
> {noformat}
> Exception from STDIN in CommandlineInterrupter.
> java.io.IOException: Bad file descriptor
>         at java.io.FileInputStream.readBytes(Native Method)
>         at java.io.FileInputStream.read(FileInputStream.java:255)
>         at java.io.BufferedInputStream.fill(BufferedInputStream.java:246)
>         at java.io.BufferedInputStream.read(BufferedInputStream.java:265)
>         at org.apache.tika.batch.Interrupter.call(Interrupter.java:52)
> {noformat}
> Further, the comments suggest that the interrupter is optional, and so it should be. :D
