For a 2.0.x kernel it can be changed by modding the sysctl file in
/proc/sys/kernel

you should just be able to do
        echo 2048 >/proc/sys/kernel/file-max

and there should be no need for a recompile.

However the libraries need to allocate a large enough structure for fdset
- which *could* be done by having you allocating a bigger chunk and
casting it to an fdset without hacking your include files... and using the
right values in the select call.

It would be possible to have squid (or other code) read
/proc/sys/kernel/file-max and then build an fdset of appropriate size and
use that.... this obviously stops working if you don't compile in proc
support, but surely no one is that sick!
