  * The last piece of this puzzle is how we actually jam ptcmalloc() into the
- * PLT.  To handle this, we have defined two functions, _malloc and _free and
- * used a special mapfile directive to place them into the a readable,
- * writeable, and executable segment.  Next we use a standard #pragma weak for
- * malloc and free and direct them to those symbols. By default, those symbols
- * have text defined as nops for our generated functions and when they're
- * invoked, they jump to the default malloc and free functions.
- *
- * When umem_genasm() is called, it goes through and generates new malloc() and
- * free() functions in the text provided for by _malloc and _free just after the
- * jump. Once both have been successfully generated, umem_genasm() nops over the
- * original jump so that we now call into the genasm versions of these
- * functions.
