In any decent operating system, the programs are prevented from  
accessing parts that would cause deadlocks, kernel panics, etc.  Pd's  
code is not causing these problems.  Pd uses code, for example the DV/ 
firewire driver, which then causes the kernel panic.

All mankind is of one author, and is one volume; when one man dies,  
one chapter is not torn out of the book, but translated into a better  
language; and every chapter must be so translated.... -John Donne
