/*
* XXX In FreeBSD 2.x, you can have the maximum number of open file
* descriptors be greater than FD_SETSIZE (which us 256 by default).
* This can lead to many RPC functions getting back an EINVAL from
* select() and bombing all over the place.
*
* You can apparently get select() to handle values larger than 256
* by patching the kernel, but most people aren't likely to know
* that. Clamping this function at 256 is a kludge, but it'll have to
* do until select()'s descriptor table size can be adjusted dynamically.
