 Junking writes some junk bytes into the area allocated.
 Junk is bytes of 0xdb when allocating;
 freed chunks are filled with 0xdf.

+By default the junk level is 1: after free,
+small chunks are completely junked;
+for pages the first part is junked.
 After a delay,
 the filling pattern is validated and the process is aborted if the pattern
 was modified.
+For junk level 2, junking is done on allocation as well and without size
+restrictions.
 If the junk level is zero, no junking is performed.
