I noticed that wiping zero pages seems to cause different behavior
of crash like:

[kmem -i]
-    SWAP USED        1         4 KB    0% of TOTAL SWAP
-    SWAP FREE   489979       1.9 GB   99% of TOTAL SWAP
+    SWAP USED   229886       898 MB   46% of TOTAL SWAP  // wiped page is counted as SWAP USED ?
+    SWAP FREE   260094      1016 MB   53% of TOTAL SWAP

I don't investigate the details yet, but I decided to slip this
feature to v1.6.4.

Thanks,
Atsushi Kumagai
