I'll mention my situation again on the wiki, but if any Tika
developers are reading this, I'd consider this a bug report! I've been
using Tika for quite a while. I use very expensive hardware to churn
through tens of millions of documents very rapidly, pulling out
plaintext and metadata. Tika has generally performed extremely well
under this stress -- never a crash or screwup!

But then one day it got about 50% slower, and I couldn't figure out
why for a while. I just happened to run 'ps xf' and noticed that Tika
was spawning all these tesseract processes. Turned out that I'd never
had tesseract installed before. I had installed it just recently for a
separate project, and Tika's behavior silently changed because of
that.

Not sure if that fits your definition of a bug, but it's certainly
unexpected behavior as far as I'm concerned!

Thanks again everyone!
