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.
