question I asked above. :) Thanks!

> When doing "tika.detect(stream, name)" and the stream is a "TikaInputStream", 
> execution gets to "TikaInputStream#getPath" which does a "Files.copy(in, 
> path, REPLACE_EXISTING);" which is very, very bad. This input stream could 
> be, as in our case, an input stream from a network file which is tens or 
> hundreds of gigabytes large. Copying it locally is a huge waste of resources 
> to say the least. Why does it do that and can I make it not do it? Or is this 
> something that has to be fixed in Tika?
