The functionality of CALLCI.HPBIN.SYS along with many other commonly
executed shell commands (including 'ls') was merged into the SH executable
quite a while ago for performance reasons (specifically to eliminate the
process creation overhead).

The result is that a callci results in a direct call to HPCICOMMAND without
any extra process creation of CALLCI.HPBIN.SYS or CI.PUB.SYS or anything
other than what might be required by the command you're executing.

If you do a :LISTF,3 on files like CALLCI and LS in HPBIN.SYS, you'll see
that they haven't even been accessed recently, since a copy of their code
exists directly in the SHell program executable.

If you explicitly execute something like

$ /SYS/HPBIN/LS *

then you'll be running the code in the external program rather than the
built in version, and you'll probably notice the extra delay involved too.
