Analysis does actually take place in a thread, so it doesn't (or at
least, hopefully shouldn't) block the UI or any other tasks, but the
actual time required to complete analysis is pretty significant - if
all of the song were analyzed, it could take days to complete the
library.  I'm not sure that I (or anyone else just testing) would be
willing to wait for that, but it wouldn't be too difficult to set it
as a user preference, if it turns out to make a significant difference
in result quality.  Something to think about, anyway...
