Tcl comes with several procedures that are actually written in Tcl as  
part of the standard library ([clock], [parray], etc.). We should  
include this code in the ParTcl source tree and use it instead of  
trying to implement them as builtins.
The library is in Tcl's CVS here:
http://tcl.cvs.sourceforge.net/tcl/tcl/library/
And don't forget the license.terms file:
     http://tcl.cvs.sourceforge.net/*checkout*/tcl/tcl/license.terms? 
revision=1.3
After this is working, builtin versions of these commands can be  
deleted.
