+ * camel-service.c (get_hostbyaddr, get_hostbyname): if we got
+ cancelled, the message is floating, so free it.
+ (struct _lookup_msg): Add a cancelled tag.
+ (camel_gethostbyname, camel_gethostbyaddr): if we get a
+ failure/cancel, cancel the lookup thread and detach, so we dont
+ have to wait for it to return. cleanup changed to handle the case
+ where we didn't get a reply message.
