I'm looking into recording some data collected by one of my programs
into rotating files.  Something like so:
ofstream ofs;
boost::archive::text_oarchive oa(ofs)
size_t rotate = 0;
for(;;)
{
foo_t foo = get_some_foo();
if (!rotate)
  {
    ofs.open(some_clever_new_filename);
    // attach oa again?
    rotate = 1000;
  }
oa << foo;
if (!--rotate)
  {
    ofs.close();
    // detach oa?
  }
}
Do I need to do anything to detach or re-attach the oarchive?

can't re-use the same archive in tis case.

I'm looking through the code trying to find the ctor and dtor for the
archives and can't find anything substantial yet; all empty dtors so
far.  Is the archive "light" enough to create/destroy with each
iteration?  Or do I need to new/delete it to keep it through the loop
iterations?
