For a unique_ptr, a deleteLater would take ownership and destroy the
moved unique_ptr on a different event loop round,
for a shared_ptr, a deleteLater would copy it and destroy the copy on
a different event loop round. The difference is
that you can't touch a unique_ptr after a deleteLater call, and if you
happen to hold on to a copy of the shared_ptr,
the deletion might not occur at all.
