 When a large (1.5MB) file is attached to a Wiki page, the upload sometimes
 ends up with the following error:

 Operational error: Database is locked

 I attempt to upload the file against a tracd standalone server (being the
 only user, performing a single HTTP request at a time), and against Apache
 2.0.53 + mod_python.

 tracd dumps the following traces on std output while the file is being
 uploaded (or before any byte transfer ?)
