pbuf_free() is some kind of garbage collector ?

No, it's a simple alloc/free mechanism, but the allocation in LWIP comes from pools of fixed-size buffers - avoiding fragmentation, and (hopefully) managing low-memory situations better, as the protocol machines should be able to handle a short-term shortage of buffers (by dropping packets) whereas the overall system heap running out is often fatal.
