/* Libc library initializer / finalizer.
 * These  functions are  bound to the  DT_INIT / DT_FINI  tags of libc.so.
 * Since use of __attribute__((constructor)) / __attribute__((destructor))
 * causes the creation of one R_386_RELATIVE relocation each (even  though
 * such a relocation  would have  been completely unnecessary  if ELF  had
 * been designed to specify pointers  apart of .init/.fini to be  relative
 * to the associated module)
 * Anyways: Anything that  cannot be  initialized lazily,  and anything  that
 *          needs to be finalized once libc.so gets unloaded (usually  caused
 *          by `exit(2)' being invoked), should  instead place a hook  within
 *          the implementation  of these  functions found  in the  associated
 *          init.c file, thus preventing the need of unnecessary relocations,
 *          as well as  making it plain  and simple to  control the order  of
