I suppose for a start reentrant versions of things can be used when
available,

#if HAVE_CRYPT_R
  {
    /* FIXME: In glibc 2.3.2, crypt_data is about 128kbytes, maybe we should
       think about mallocing it so as not to abuse the stack. */
    struct crypt_data data;
    data.initialized = 0;
    return scm_makfrom0str
      (crypt_r (SCM_STRING_CHARS (key), SCM_STRING_CHARS (salt), &data));
  }
#else
  return scm_makfrom0str
    (crypt (SCM_STRING_CHARS (key), SCM_STRING_CHARS (salt)));
#endif
