Re: [PATCHv2 4/4] first use of sys_indirect system call

[dean gaudet <dean@arctic.org>]

you know... i understand the need for FD_CLOEXEC -- in fact i tried 
petitioning for CLOEXEC options to all the fd creating syscalls something 
like 7 years ago when i was banging my head against the wall trying to 
figure out how to thread apache... but even still i'm not convinced that 
extending every system call which creates an fd is the way to do this.  
honestly i think there should be a per-task flag which indicates whether 
fds are by default F_CLOEXEC or not.  my reason:  third party libraries.

i can control all my own code in a threaded program, but i can't control 
all the code which is linked in.  fds are going to leak.

if i set a per task flag then the only thing which would break are third 
party libraries which use fork/exec and aren't aware they may need to 
unset F_CLOEXEC.  personally i'd rather break that than leak fds to 
another program.

but hey i'm happy to see this sort of thing is finally being fixed, 
thanks.
