Follow-up Comment #1, bug #25695 (project lwip):
Rhe fix you propose seems to be good at the first sight.
But perhaps I'm wrong, I think the problem is more in the unix port : in
contribportsunixsys_arch.c, the sys_mbox_trypost implementation use a call to
sys_sem_wait, which cause the "switching" to tcpip_tcp_timer, causing the
reentrance problem.
Perhaps replacing sys_sem_wait by sys_arch_sem_wait in sys_arch.c good fix
this problem...
