an executable has been deleted and recreated. The only thing that
makes this reasonable is that st_mtime doesn't change when a file
is unlinked, so saving st_mtime makes BFD's file cache operation
a little more transparent for this particular usage pattern. If we
hadn't closed the file then we would not have lost the original
contents, st_mtime etc. Of course, if something is writing to an
existing file, then this is the wrong thing to do.
FIXME: gdb should save these times itself on first opening a file,
and this hack be removed. */
