Yes, of course. I took that as a given, based on the way that Ben is recycling
his objects.

Indeed. That's what lies behind the OP's predicament. If init did it, he
would not have to hack around like this. Pity us poor C++ folks. One of the
worst design decisions in C++, IMO, is that objects are not zeroed on
allocation by default. It leads to constructors like this:
ivar1 = 0;
ivar2 = 0;
ivar3 = 0;
ivar_p1 = NULL;
ivar_p2 = NULL;
...
Which is tedious and error prone.
