I vaguely remember that in the past (> 10 years ago) it was possible
to put the select calls into their own compilation unit (.c -> .o) and
there, before #including any of the usual socket stuff, #define
FD_SETSIZE or something like that to a larger value, to make select
support more than 1024 descriptors - the limit basically having been a
userlevel one for the fd_set definitions from the headers, not a
kernel side one. Might have changed meanwhile, though, but I thought
I'd mention it :)
