To (part) answer my own question...

Within the TCP_REG_ACTIVE() definition there is a call to tcp_timer_needed()
which eventually makes its way to sys_now().
It appears that my sys_now() function is hanging despite the fact it worked
when being used in the DHCP process and the UDP connection that entailed.
I guess this makes it something dumb I've done in the port rather than the
stack itself!
