emfile error

[Per Bergqvist]

Under most Unices this is also limited by SC_OPEN_MAX|NOFILE or       
similiar.                                                             
BSDI also restricts it to FD_SETSIZE.                                 
Under Win32 there is a strange restriction (hardcoded) to 1024.       
(WinNT/2K/XP is actually only restricted by available memory for fds).
                                                                      
Hack you sys.c to fix it.
