Follow-up Comment #6:

I found a problem with this patch: with the current code, timeouts get delayed
when you're in a debugger breakpoint and your sys_now() continues running
while you're stopped.

This is because sys_now() actually continued, say 50 seconds, but
sys_check_timeouts() increases timeouts_last_time only by the expired
timeout's time. If that handler restarts a timeout (as is the case for all
lwIP-internal timers), it gets an addditional delay of 50 seconds.
