I wrote the prefetcher and I disagree. If you mount a file system, there is a 
reasonable expectation that it works like a local filesystem - meaning that it 
is fast. The prefetch caching is not designed and suited for that case.

But the worst is that this change breaks ASF and AVI demuxers.

The applies to network FS, and to userspace FS.
