If that process writes to the file, then the file might go corrupt. There have been a few historical bugs in SQLite now fixed that could cause database corruption. Deleting a hot journal SQLite normally stores all content in a single disk file.
So the solution should be simple: For exactly this reason, SQLite has a lock timeout built in. So, for example, a device would be writing content into an MP3 file in flash memory when a power loss occurs, and that could result in an SQLite database being corrupted even though the database was not even in use at the time of the power loss.
Other incompatible changes, such as a cleanup of the API, were introduced at the same time under the theory that it is best to get your incompatible changes out of the way all at once. And there is a collection of routines used to implement user-defined SQL functions and user-defined text collating sequences.
SQLite must see the journal files in order to recover from a crash or power failure. I think there are two lessons here: The mystery was solved. Eventually, one incredibly helpful user offered to give me guest SSH access so I could see the bug manifest in vitro on his machine.

Unbound wildcards have a value of NULL. You can also forget about embarrassing papers with paraphrased chapters from your book and sources like Wikipedia in the bibliography. One would think this would be harmless. But if the journal file does exist, it must be kept together with the database to avoid corruption.
