streamToFileSystem asynchronous?

[Brad Grier]

I saw a handful of these in our logs just after a restart. I was under the impression that streamToFileSystem was asynchronous but this looks like it could block (although I wouldn't expect File.exists() to block this long - hardware issue?). Anyway, would I be better off handling an uploaded file in another manner? I'm using 3.2.0.
