Summary: namespace / trace double-free crash

Initial Comment:
The following code creates a double-free situation in 
Tcl 8.3.4/8.4a4:

    namespace eval ::foo {
	variable x 123
    }
    proc p1 args {
	trace vdelete ::foo::x u p1
    }
    trace variable ::foo::x u p1
    namespace delete ::foo

I've correct this with the attached patch for 8.3.4 
(and am applying a similar patch for 8.4a4).
