You must, however, be aware of multitasking issues, certainly on a web
site. When more than one request comes in at your site at approximately
the same time and they want to make modifications in your database, the
modifications may interact in a non-intended way, even to the point that
they may corrupt your database. Some file locking should be applied to
serialize the updates (and probably the reads as well with respect to the
updates). Metakit doesn't have record locking, unfortunately.
