I agree with your assessment. I think your proposal is part of the solution.

Configured LWIP with pretty much default options apart from TCP/IP and sockets API disabled (UDP enabled, no DNS, DHCP etc). Under these circumstances the LWIP_NUM_SYS_TIMEOUT_INTERNAL declaration in "./src/include/lwip/opt.h" evaluates to 2.

Addendum:
5. Note in documentation why a user might want to set MEMP_ADD_NUM_SYS_TIMEOUT.
Steps 4 & 5 are assuming there remains some reason to even allow MEMP_NUM_SYS_TIMEOUT to differ from LWIP_NUM_SYS_TIMEOUT_INTERNAL, after implementing steps 1-3.
