Gerd recently turned on some string debugging code in alloc.c (see
GC_CHECK_STRING_BYTES).  When that happened I noticed an obvious
slowdown (actually it checks things every 50 calls to `allocate_string';
initially it did so every *10* calls, and that was truly insane...).

The effect on speed is obviously related to string usage; for instance,
I've noticed that reading in ja-dic/ja-dic.elc seems particularly slow.
