  1.1977 05/12/13 21:35:24 aivanov@stripped +10 -0
  Fix BUG#12071: "Windows hang:'Opening tables' or 'Waiting for
   table' lockup".
   Changes from the innodb-5.0-ss92 snapshot.
   Do not call os_file_create_tmpfile() at runtime. Instead, create
   all tempfiles at startup and guard access to them with mutexes.
