Pbuf allocation fails because all pbufs are already used elsewhere in the 
code, or because there is no heap memory for allocating the buffer. There are 
problems with memory usage in the 0.4.2 version that will be retified in the 
0.5 version. 

I have no schedule for the 0.5 version, but most of the code is ready and can 
be found in the CVS (downloadable from the homepage). There are a few issues 
in the unix port that I would like to fix before the 0.5 is officially 
released.

Notice that the sys_arch stuff is different (and simpler!) in the 0.5 
version. See the other thread on "RFC - new sys_arch for lwIP 0.5".
