66# Test an unusual scenario:
67#
68#   1. A wal mode db is opened and written. Then sqlite3_close_v2() used
69#      to close the db handle while there is still an unfinalized
70#      statement (so the db handle stays open).
71#
72#   2. The db, wal and *-shm files are deleted from the file system.
73#
74#   3. Another connection creates a new wal mode db at the same file-system
75#      location as the previous one.
76#
77#   4. The statement left unfinalized in (1) is finalized.
78#
79# The test is to ensure that the connection left open in step (1) does
80# not try to delete the wal file from the file-system as part of step
81# 4.
