The NSLog(v) documentation says:
NSLogv writes the log to STDERR_FILENO if the file descriptor is
open. If that write attempt fails, the message is sent to the syslog
subsystem, if it exists on a platform, with the LOG_USER facility
(or default facility if LOG_USER does not exist), with
priorityLOG_ERR (or similar). If both of these attempts to write the
message fail, the message is discarded.
This is not true. Even though I've redirected STDERR_FILENO to my own
log file, using dup2, the messages still go into system.log. (Yes,
they are going into my log file, too.) This is very annoying because
it wastes disk space and makes syslogd spin, burning up CPU.
This is on Leopard; I don't remember if it also happened on Tiger.
Is this a known bug? Is there any way to stop it?
