	Ah.  The bug is that I'm not validating keys in get bulk.  You're  
passing in a single key with spaces in it.

	I'll make sure these are validated, but in the meantime, this is how  
your code should look:

private Map<String, Object> getStuff(Collection<Integer> ids) {
     Set<String> keys=new HashSet<String>();
     for (int id : ids) {
	keys.add("cacheditem:" + id);
     }
     Map<String, Object> map = memcache.getBulk(keys);
     log.debug("Requested "+ids.size()+" items from cache, got  
"+map.size()+" items back");
     return map;
}
