Minor correction ... that's the process ID, not a byte count.

No ... the point about NSLog is to report a standard log format with 
information about the process logging etc, so the prefix is mandatory (though 
there *is* an option to get it to report thread ID as well as process ID).

That said, It's possible to set a default to have NSLog output go to syslog 
rather than stderr, and it's also possible to intercept the logging in your 
code (you should read the NSLog documentation for details) and do what you like 
with it.

But, if you really don't want the header produced by NSLog(), you can simply 
call fprintf(stderr,...) instead.
