I think some spamming is okay, as long as it's not going on forever. 
Perhaps even 10 times is enough (I'm not going to ask you to introduce a 
rate limiting like printk's :)).

Adding this to the monitor can be useful even separately from the stderr 
spam.  Perhaps you can add the current drift to "info jit" if you feel 
it is useful.  You are user #0 of the feature, so your guess is better 
than mine.
