While discussing bug #47485, we kind of decided that it would be good for the 
core
code to not fail with ERR_MEM (i.e. out of pbufs when enqueueing the FIN) but 
just
retry to enqueue the FIN from tcp_tmr(). The result would be pretty much the 
same
as your code you explained but it would be there once and for all...

That's future talk, though.
