Race Conditions

[eriq-augustine]

There are race conditions all over the place.
In pretty much every operation.

The real question is how we decide to handle them.
Should we:

• lock the driver on every command
• lock on the file level
• force the external caller to lock

At the driver level, the only critical concern is that that fat is not corrupted.
We will even tolerate things like incorrect access dates or counts as long as the filename and iv remains intact.
