[basex-talk] Detecting abandoned locks

Howdy --

I have a BaseX database with a pin-* file in its directory, reporting as locked and unavailable. However, OS-level tools such as fuser report that no programs have open file handles for any processes in this directory.

What mechanism does BaseX use for detecting abandoned locks? It would be nice to use OS-level advisory locking where available, such that the lock is automatically released whenever the program holding it exits (or otherwise ceases to hold a handle on the file).
