When you make a change to a system call, you should always check
if the change makes sense for the 32 bit emulation path as well.
In this case, you should definitely do the same thing to both
sys_select and compat_sys_select if this is found worthwhile.

Please describe what aspect of the syscall is improved. Is this only
speeding up the execution for the delay case while slowing down
the normal case, or do the actual semantics improve?
