See RFC 1122, 4.2.2.17  Probing Zero Windows.  The RFC suggests that retransmission timer and zero-window probing may be able to be a shared mechanism since they both use exponential backoff and have a fixed maximum timeout

We can combine the two mechanisms to reduce TCP variables in the pcb and also hopefully reduce code size

We should also audit our timeouts to make sure they follow guidance in RFC 1122 section 4.3.2.5 TCP Connection Failures.  Be sure to check for any newer RFC on this topic and possibly study other stacks maximum timeouts (Linux/FreeBSD/NetBSD)
