// to use its own custom ref-counting code. However, that would require
// using multiple inheritence, which sucks in general. And to make matters
// worse, it causes problems with our New<> and Delete<> wrappers.
// Specifically, unless RefCounted is first in the list of parent classes,
// it will see a different value of the address of the object than the one
// we actually allocated, in which case gpr_free() will be called on a
// different address than the one we got from gpr_malloc(), thus causing a
// crash. Given the fragility of depending on that, as well as a desire to
// avoid multiple inheritence in general, I've decided to leave this
// alone for now. We can revisit this once we're able to link against
// libc++, at which point we can eliminate New<> and Delete<> and
// switch to std::shared_ptr<>.
