Did you recompile the programs? Most or all of those programs use nlist() 
to snarf into the kernel through /dev/kmem.  chances are the internal data
structures of the kernel changed and they will start working again when 
you recompile with the new .h files.  Anything that plays with kmem (nasty
habit, that....) is susceptible to this.  I'd guess you got caught.

Dessert is probably the most important stage of the meal, since it will be
the last thing your guests remember before they pass out all over the table.
