# This test verifies that closing database handles does not drop locks
# held by other database handles in the same process on the same file.
#
# The os_unix.c module has to take precautions to prevent this as the
# close() system call drops locks held by other file-descriptors on the
# same file. From the Linux man page:
#
#   close() closes a file descriptor, so that it no longer refers to any file
#   and may be reused. Any record locks (see fcntl(2)) held on the file it 
#   was associated with, and owned by the process, are removed (regardless 
#   of the file descriptor that was used to obtain the lock).
