[PATCH] Enables lock work under the other 'OS'
From: K Thananchayan <thananck@yahoo.com>
os.symlink is not supported under Windows. This patch
introduces util.mklockf, util.getlowner that use
regular files under Winodws but symlink under unix.
tweaked by mpm:
- changed function names
- fixed to work on UNIX
