Hm...reading the links, references and quick googling shows that this
problem is extX specific and other FS may handle delete right without IOpain.
Feels like this algorithm better to make configurable and notify admins about
such problem and the option, but I would like to make some benchmarks for FS I
uses for CouchDB: XFS and ZFS. Though for XFS this [shouldn't be a
problem](http://www.bullopensource.org/ext4/20070404/FileDeletion.html) already.
