 (XXX: kern.ps_strings and kern.usrstack are prime examples of the 4/8 byte
  long problem).
 
+Fix sysctl(2) int/long mess, especially for kern.ps_strings and
+kern.usrstack.  The current hack is Just Wrong.  What is needed is a
+syscall wrapper for it that downconverts the "long" values from 64 bit to
+32 bit for the 32 bit binaries.  This is going to need a table of important
+"long" sysctls to translate.

   but gcc-3.3 would be much better)
