 Hi, moving this here from the later comments in #1276.

 a G_fatal_error() while a db_driver is open, such as you get when you typo
 the name of an attribute column, does not close the db driver, which is
 left behind as a zombie process (along with a dependent cmd.exe). This is
 a problem as the db driver may be holding a file open, blocking anything
 else from working on it or removing it.

 db_close_database_shutdown_driver() seems to shut it down properly.

 work-around: ctrl-alt-del to the task manager and kill any dbf.exe
 processes. the cmd.exe ones will then go away.

 maybe this program helps: (lsof for Windows)
