 When an error occurs on file upload in the media uploader while drafting a
 post, the error message persists after both a) another file is
 successfully uploaded, b) the media manager is closed and re-opened.

 In both of these cases, it is my opinion that the user is best served by
 having the error message automatically dismissed, as

 1. Its positioning is not typical of a "historic/cumulative" error log,
 2. It may be assumed that by successfully uploading another file the error
 first encountered is no longer relevant, and
 3. An indefinite amount of time may have passed since the error was first
 encountered and the media manager subsequently closed and the next time
 the media manager/upload div was re-opened such that the user may have
 completely forgotten about the error and may be confused to see a red
 error box and mistakenly think it is associated with some action he/she
 just took,
 4. As a dialog, nothing about the media manager suggests that its state
 should persist after being closed and re-opened.

 (see attachment as an example of an error)
