Follow-up Comment #15, patch #9523 (project lwip):

I'm not sure that assuming different devices will have unsynchronized periodic
timer will be ok. If sys_now() implementation is base on gettimeofday() for
example (well I know, this is a bad thing), and this one in keep sync using
NTP, this result in periodic timer sync across all devices.

Personally, I prefers a TRUE random time against request reception. A faster
on-demand tick (5ms) with a random counter may do the job anyway.
