In the case of sh.hpbin.sys, the problem isn't simply having the CTRL-Y trap
enabled, rather it's enabling then disabling the trap for EVERY LINE OF SHELL
SCRIPT.  The performance results aren't pretty for monster scripts like
Perl Configure (~12000 lines).

Since 5003435362 doesn't appear to be visible on the HP ESC, you'll need to
open a new HPRC call to ask about its status.  While you're at it, complain
that more SRs need to be visible on the HP ESC.  :-(
