  Added the test for issue3762.

  More strict test. Consider the case sys.executable itself is symlink.

  more intensive test on dbm.
........
  r66862 | hirokazu.yamamoto | 2008-10-09 19:00:30 +0900 | 3 lines

  On windows, os.chdir given unicode was not working if GetCurrentDirectoryW

  really executed because I cannot move to such directory on win2k)

  r66862 contained memory leak.
