Subject:   default file descriptor limit ?

	$ limits
	Resource limits (current):
	[...]
	openfiles              462357

say what ?

This wastes tons of pointless close system calls in programs which
use the suboptimal but best practice:

	for (i = 3; i < sysconf(_SC_OPEN_MAX); i++)
		close(i);

For reference Linux seems to default to 1024, leaving it up to
massive server processes to increase the limit for themselves.

I'm all for autosizing things but this is just plain stupid...

Never attribute to malice what can adequately be explained by incompetence.
