I agree with that one and like to add another thought. If I remember 
correctly, I tried to replace NutHeapAlloc/Free by malloc/free some time 
ago, but had to revert this change because of link sequence problems. 
Since Nut/OS uses -Wl,--start-group and -Wl,--end-group, link sequence 
problems are gone and it may be save now to use malloc/free in the 
application layer network code. This will make it a bit easier to port 
this code to other operating systems.
