i dont think that this is worth the effort. usually the program runs a lot
faster than any network device can supply enough data to fill up the
buffers. the buffer overflows are rarely seen. i think we only managed to
see it with a local mass-client test on a heavily loaded machine,
definitly not with < 1024 open files.

but feel free to send patches :-) perhaps such a check can be made when
the select/poll structures are built. watch out to not include more
overhead then you gain in speed...
