Subject: sys_indirect or many syscalls?

Linux,
will you please make a decision regarding sys_indirect? There has been
no other proposal so the alternative is to add more syscalls.
This really is a problem. For one instance, see
http://bugzilla.redhat.com/show_bug.cgi?id=443321
The problem is actually a socket call and we cannot reliably set the
CLOEXEC bit without massive program slowdowns. This is just one example.
I still think the sys_indirect method is the best since it avoids bloat
in the number of system calls.
