b1392e7c17 Properly round the allocated set vector space; reduces by one the number 
of ways in which C++ programs will dump core.

c83756b171 Careful when claiming jump slots in the "force alias" case. 
Taking the address of a function must not cause it to be relocated to
a possibly already allocated jump slot. C++ virtual function tables are
an example of this.
