  23 /* I don't recommend using this interface in general.  Use `free'.
  24  *
  25  * I'm told Microsoft Windows may use one set of `malloc' and `free'
  26  * in a library, and another incompatible set in a statically compiled
  27  * application that link to the library, thus creating problems if the
  28  * application would invoke `free' on a pointer pointing to memory
  29  * allocated by the library.  This motivated adding this function.
  30  *
  31  * The theory of isolating all memory allocations and de-allocations
  32  * within a code package (library) sounds good, to simplify hunting
  33  * down memory allocation related problems, but I'm not sure if it is
  34  * worth enough to motivate recommending this interface over calling
  35  * `free' directly, though.
  36  *
  37  * If you have any thoughts or comments on this, please let me know.
