You need to write a custom allocator in C and recompile Python. 
Look at Include/pymem.h : 

/*
 * Core memory allocator
 * =====================
 */

/* To make sure the interpreter is user-malloc friendly, all memory
   APIs are implemented on top of this one.

   The PyCore_* macros can be defined to make the interpreter use a
   custom allocator. Note that they are for internal use only. Both
   the core and extension modules should use the PyMem_* API.

   See the comment block at the end of this file for two scenarios
   showing how to use this to use a different allocator. */
