Agreed, all applications would have to be switched over to using poll()

I don’t see how this issue could be worked around since there is only expected 
to be a single instance of LwIP socket layer (and FDs) in the system, not an 
instance per process.  For GNU Hurd deployment, is LwIP only being used in a 
single process?  Or is there no desire to use select for GNU Hurd?

Another thing to consider might be how LwIP was integrated into MINIX3.  They 
wrote their own socket layer and only used LwIP's RAW API.
