Review Comment:
   This is legit.

> Currently ProcessUtils.execute starts a subprocess, even if 
> requestedTimeoutMillis is 0. TikaHttpClient on the other hand has a fail fast 
> path, where a timeout exception is thrown, if the granted timeout is <= 0.
> ProcessUtils.execute should probably also have a fail fast path similar to 
> the TikaHttpClient.
