It's OK, but if you have a lot of files to check and they're large, and
changes frequent, it could put the system under severe workload.

If you just need to know if a file has changed, you can check via
date/time, or if you don't trust somebody who's got access to it (because
he could have manually altered the datetime) you could go for a simpler
algorithm, like sfv.
