You can skip the HTTP background deletion, by editing 
htscore.c, and deleting the following lines:

  for(i=0;i<back_max;i++) { \
  back_delete(&opt,&cache,back,i); \
  } \

.. as the program will exit anyway after that.

You can similarly erase:

  if (liens!=NULL) { \
  for(i=lien_max-1;i>=0;i--) { \
  if (liens[i]) { \
  if (liens[i]->firstblock==1) { \
  freet(liens[i]); \
  liens[i]=NULL; \
  } \
  } \
  } \
  freet(liens); \
  liens=NULL; \
  } \
