Follow-up Comment #10, patch #5960 (project lwip):
>Note, than now, timeouts are mainly used by tcpip_thread (exceptions are
select & PPP)...
Select doesn't use timeouts, only tcpip_thread and PPP.
But if another thread (api thread before your last checkin changing
sys_mbox_fetch to sys_arch_mbox_fetch) waits parsing timeouts and parses the
timeout list of tcpip_thread, the core is very likely to crash! Therefore,
for the current implementation, per-thread storage _is_ necessary.
What you do (static table indexed per task id) is a workaround that can be
used for system not supporting per-thread storage but is (almost for sure)
slower than direct per-thread storage. I think we should keep the speed of
that in mind while re-designing!
