Before:

After:
unique_lock<mutex> lock(some_mutex);
// make copy of object on heap protected by mutex lock
auto tmp_copy = foo[bar];
// run lock.~unique_lock() because return
// pass locally allocated object to copy constructor
return tmp_copy;

Get rid of the ResourceHolder class.
Fix GCC static template member instantiation issues.
Replace assert() with exceptions.
shared_ptr can't seem to do reference counting in a multi-threaded
environment. The code looks correct (for both ResourceHandle and
std::shared_ptr); however, continual segfaults don't lie.
Carpet-bomb with mutex locks to reduce the likelihood of losing shared_ptr
races.
