The # of fd's available to the entire system can be increased by
echoing values to /proc. That's easy.

On most Unixes, you can make one syscall and up your # of fd's per
process to 1024 or 4096 or more. That's easy and standard.

In Linux, upping the # of fd's available to invididual processes
involves a kernel recompile, and a glibc recompile, and then all
processes get larger. This is not what I would call "easy". Um, do you
also have to recompile all RPMS? I'd have to think about that.
