BTW there are a number of 3rd party libraries that have builtin FD_SETSIZE
limitations. An app that really wants to make use of lots of descriptors
has to play stupid games anyhow. (Witness apache-1.2.1's ap_slack()
function to keep low numbered descriptors free for use by lame libraries
... gag.)
Keeping a default soft-limit of 256 is good for backwards compatibility.
