Ehrm, unless everything in lwIP runs on that interrupt level and *not* 
in main loop (or a thread), that's OK. If not, sooner or later, you'll 
get a problem!

This doesn't depend on the callback run time vs. system response time. 
If it just happens that lwIP is processing timers while your callback 
fires, you'll have a problem.
In the end, just don't try to use a library in a way that it wasn't 
meant to!
