History
Robert Watson f8efde8991 - Teach SIGIO code to use cr_cansignal() instead of a custom CANSIGIO() 
macro.  As a result, mandatory signal delivery policies will be
  applied consistently across the kernel.

- Note that this subtly changes the protection semantics, and we should
  watch out for any resulting breakage.  Previously, delivery of SIGIO
  in this circumstance was limited to situations where the subject was
  privileged, or where one of the subject's (ruid, euid) matched one
  of the object's (ruid, euid).  In the new scenario, subject (ruid, euid)
  are matched against the object's (ruid, svuid), and the object uid's
  must be a subset of the subject uid's.  Likewise, jail now affects
  delivery, and special handling for P_SUGID of the object is present.
  This change can always be reversed or tweaked if it proves to disrupt
  application behavior substantially.
