It's very likely to be your port - I don't recall any recent bugs due to
select timeout problems (but it might be wise to do a quick search of
the lwip-devel mailing list just to be sure).  

You could try upgrading to 1.3.2 in case there was a problem in the
stack, or the port you're using, that got fixed in the upgrade.

The timeout is implemented (in current lwIP at least) using
sys_sem_wait_timeout(), which in turn uses sys_arch_sem_wait() which
will be part of your port.  You should be able to look at how this
operates to check its behaviour.
